It is connected in series with a resistance and an accumulator of emf 2V and of negligible internal resistance. A source of emf 10 mV is balanced against a length of 40 cm of the potentiometer wire.

What is the value of the external resistance? Using this diagram, derive the relation. Write the sign conventions used. What happens to the focal length of convex lens when it is immersed in water? The two sides, of the coil, of length 0. One of them is at a distance of 0. The wire is in the plane of the coil. Calculate the magnetic flux through the rectangular coil. If the current uniformly to zero in 0. A wheel with 10 metallic spokes each 0. By increasing the height of the receiving antenna, so that it may directly intercept the signal from the transmitting antenna.

From the relation we find that an extremely minute field bends charged particles in a circle of very large radius. Over a small distance, the deflection due to the circular orbit of such large R may not be noticeable, but over the. Two electric field lines never cross each other. If they intersect, then there will be two directions of electric field at the point of intersection which is not possible. This current is much smaller than for the low frequency showing that the inductive reactance is very large at high frequency and L nearly amounts to an open circuit.

This frequency is greater than the critical frequency and ionosphere cannot reflect it. The co-axial cables and wires are extremely radiating in nature at this high frequency. Since the -particle is momentarily stopped at a distance x, its initial kinetic energy is completely changed into potential energy here.

Let us take a charged conductor with the hole filled up, as shown by shaded portion in the figure. We find with the application of Gaussian theorem that field inside is zero and just outside is. This field can be viewed as the superposition of the field E2 due to the filled up hole plus the field E1 due to the rest of the charged conductor. The two fields E1 and E2 must be equal and opposite as the field vanishes inside the conductor. Intensity is proportional to width of slit. So, amplitude a1 and a2 I proportional to the square root of the width of the slit.

For diffraction or bending of waves by obstacles or apertures by a large angle, the size of the latter should be comparable to wavelength. Here the size of partition wall is of the order of a few meters.

The wavelength of light is about 5 m, while sound wave of say 1 kHz have wavelength of about 0. Thus, sound waves can bend around the partition while light waves cannot. Input and output waveforms of half wave and full wave rectifier are shown in figure. Half wave rectifier conducts once during a cycle and full wave rectifier does so twice.

Therefore, if input frequency is 50 Hz, output frequency for half wave and full wave rectifier are 50 and Hz respectively. Let AB be the potentiometer wire and R, the external resistance, as shown in the figure. Which must be equal to the emf of the source when the balance is achieved. Consider a point object O placed on the principal axis. The ray along ON goes straight and meets the previous ray at I. Thus I is the real image of O. The speed becomes very high as the jogger approaches the car.

The change in speed can be experienced by anybody while travelling in a bus or a car. Magnetic field, due to wire, at the location of the coil is perpendicular to the plane of the coil and directed inwards. When current is reduced to zero, this magnetic field decreases. To oppose this decrease, induced current shall flow clockwise, so that its magnetic field is also perpendicular to the plane of the coil and downward.

Explain qualitatively on the basis of domain picture the reversibility in the magnetization curve of a ferromagnet. What is the longest wavelength of radio waves, which can be sent between the towers without appreciable diffraction effects?

What reasoning led de-Broglie to put forward the concept of matter wave? The wavelength , of a photon, and de-Broglie wavelength associated with a particle of mass m has the same value, say. Show that the energy of photon is times the kinetic energy of the particle.

Another source of monochromatic light produces the interference pattern in which the two consecutive bright fringes are separated by 8 mm. Find the wavelength of light from the second source.

What is the effect on the interference fringes if the monochromatic source is replaced by a source of white light? What are coherent sources? State the basic electronic circuit involved in the electronic circuit of figure and find the value of the output y. Name the gate formed and set up a truth table for it. The separation between the plates of a charged capacitor is to be increased.

Explain when work done will be more in case battery is removed after charging the capacitor or battery remains connected. The maximum current carrying capacity of a given coil of wire is 15 A and the number of turns per unit length that can be wound round a core is at most turns m Suggest some appropriate design particulars of a solenoid for the required purpose.

Assume the. A radioactive sample contains 2. Eight identical resistors r, each are connected along the edges of a pyramid having square base ABCD as shown in figure below. Calculate equivalent resistance between A and B. Solve the problem. An angular magnification of 30X is desired using an objective of focal length 1. How will you set up the compound microscope? How far from the objective should an object be placed in order to obtain the final image at.

Give one example to illustrate this law. The atomic dipoles are grouped together in domains in a ferromagnetic substance. All the dipoles of a domain are aligned in the same direction and have net magnetic moment. In an unmagnetised substance these domains are randomly distributed so that the resultant magnetization is zero. These domains align themselves in the direction of the field when the substance is placed in an external magnetic field.

Some energy is spent in the process of alignment. These domains do not come back into their original random positions completely when the external field is removed. Some magnetization is retained by the substance. The energy spent in the process of magnetization is not fully recovered.

The balance of energy is lost as heat. This is the. Yes, a charged body can attract another uncharged body.

When the charged body is placed near the uncharged body, the induced charges of opposite kind are produced on the uncharged body and the uncharged body is attract by charged body. Increasing the number of turns in the galvanometer coil. Decreasing the torsion constant of the suspension fibre. Mode of radio wave propagation by space waves, in which the wave travels in a straight line from transmitting antenna to the receiving antenna, is called line of sight LOS communication.

Two types of waves that are used for LOS communication are : space wave and. Where is constant frequency of carrier wave and is instantaneous frequency of the FM wave at any time t. He reasoned that nature is symmetrical and that the two basic physical entities, matter and energy must have symmetrical character. If radiation shows a dual nature, so should matter. If monochromatic source is replaced by white light. We will not fringes on screen as the white light slits will not act as coherent sources of light.

Two sources which produce waves of same frequency and the phase difference of produced waves does not change with time then the sources are said to be coherent sources.

The fringe width decreases of the distance D between the slits and screen is decreased. The fringe width decreased if the frequency v of the source is increased. The electronic circuit shown is a bubbled AND gate. Clearly, more work is required to be done in the first case. Let A is the area of the two plates of the parallel plate capacitor and d is the separation between them. The total electric field inside the dielectric slab will be: where is the opposite field developed inside the slab due to polarization of slab.

Consider a battery connected between A and B. The circuit now has a plane of symmetry. Now, OA and OB can be treated as a series combination which gives resistance Also DO and OC are in series combination. This gives 2r. It is in parallel with DC. This gives a resistance of or. This is in series with resistances AD and CB. This gives i. If R is the equivalent resistance, then. The final image will be formed at infinity only if the image formed by the objective is in the focal plane of the eyepiece.

The smaller loop is so small in area that one can take the simple formula for field B on the axis of the bigger loop and multiply B by the small area of the loop to calculate flux without much error. It means that the induced emf is such that, if the circuit is closed, the induced current opposes the change in flux. Name the absorbing material used to control the reaction rate of neutrons in a nuclear reactor. Does the apparent depth of a tank of water change if viewed obliquely?

If so, does the apparent depth increase or decrease? What is the direction of induced current in the metallic loop kept above the wire as shown in the figure? How does the mutual inductance of a pair of coils change when the number of turns in each coil is decreased? A long solenoid of 20 turns per cm has a small loop of area 4 cm2 placed inside the solenoid normal to its axis. If the current by the solenoid changes steadily from 4 A to 6A in 0.

Suppose you are given a chance to repeat the alpha particle scattering experiment using a thin sheet of solid hydrogen in place of the gold foil. Hydrogen is a solid at temperatures below 14 K.

Draw the i symbol and ii the reverse I-V characteristics of a zener diode. Explain briefly, which property of the characteristics enables us to use Zener diode as voltage regulator.

Name the electromagnetic waves used for the following and arrange them in increasing order of their penetrating power. Two concentric coplanar semi-circular conductors form part of two current loops as shown in the figure. If their radii are 11 cm and 4 cm, calculate the magnetic induction at the centre.

A mono energetic 18 keV electron beam initially in the horizontal direction is subjected to a horizontal magnetic field of 0. Estimate the up or down deflection of the beam over a distance of 30 cm.

Given mass of electron and charge on electron. Two charged conducting spheres of radii a and b are connected to each other by a wire.

What is the ratio of electric fields at the surfaces of the two spheres? Use the result obtained to explain why charge density on the sharp and pointed ends of a conductor is higher than on its flatter portions. In 1, flux decreases and so induced current must be clockwise to increase the flux. Due to the same reason currents in 3 and 4 are clockwise but in 2 current must be anticlockwise as flux is increasing.

As the dielectric constant of a medium is the ratio of forces between two charges placed in vacuum and medium without no change in magnitude of charges and their distance.

The force will increase. Spherical b. Plane c. Plane Because a small area on the surface of a large sphere is nearly planar. In ground wave propagation, loss of energy due to interaction with matter increases with the increase in frequency. Frequencies above kHz get heavily damaged. So ground wave propagation is restricted to a frequency of kHz. For the detection of explosives, opium and gold in the body of the smugglers.

In detecting fractures, diseased organs in human body. This is because magnetic lines of force are continuous closed loops and mono pole is not possible. The nucleus of a hydrogen atom is a proton mass which has only about one-fourth of the mass of an alpha particle. It is like a bowling ball colliding with a ping pong ball at rest. Thus, there would be no large angle scattering in this case. The analogy there is a ping pong ball hitting a bowling ball at rest. It can be proved by contradiction.

Assume that the test charge placed at null point be in stable equilibrium. The test charge displaced slightly in any direction will experience a restoring force towards the nullpoint as the stable equilibrium requires restoring force in all directions. That is, all field lines near the null point should be directed inwards towards the null point. This indicates that there is a net inward flux of electric field through a closed surface around the null point.

But, according to Gauss law, the flux of electric field through a surface enclosing no charge must be zero. This contradicts our assumption. Therefore, the test charge placed at null point must be necessarily in unstable equilibrium. On the mid point of the line joining the two charges, the null point lies. The test charge will experience a restoring force if it is displaced slightly on either side of the null point along this line. While the net force takes it away from the null point if it is displaced normal to this line.

That is no restoring force acts in the normal direction. But restoring force in all directions is demanded by stable equilibrium, therefore, test charge placed at null point will not be in stable equilibrium. The maximum kinetic energy of emitted photoelectron is independent of intensity of light.

For each photoelectron, there must be a threshold frequency of incident light below which no emission takes place. For the metal of work function. The kinetic energy of photoelectron emitted due to falling of photon of frequency is. Zener diode as voltage regulator: For widely different Zener currents, the voltage across the Zener diode remains constant.

On account of this fact we can use Zener diode as a d. Thus, for. Water purification — Ultra violet waves b. Rewrite sensing — Micro waves c. Treatment of cancer — Gamma rays. It is a case of two equal resistors connected in parallel. So, current in each resistor is 1A. Let us now consider resistors between C and D. It is a parallel combination of two resistances. Current would be divided in the inverse ratio of resistances. If I1 is the current through and I2 is the current through , then.

So, current through resistor is. Similarly, current through resistor is. Since the circuit is infinitely long, its total resistance remains unaffected by removing one mesh from it. Let the effective resistance of the infinite network be R. The effective resistance of the remaining part of the circuit beyond CD is also R.

The circuit can be recombined as shown in figure b. The resistance R and are in parallel. Their combined resistance is. The total combined resistance is: Which must be equal to the total resistance of the infinite network. Since R can not be negative. Magnetic field on the normal bisector at a distance r from the centre.

Thus, for the same distance on the axis as the distance of the null point, the total field, using equations i and iii is. Suppose that two connected conducting spheres of radii a and b possess charges q1and q2respectively.

On the surface of the two spheres, the potential will be. Till the potentials of two conductors become equal the flow of charges continue. Therefore, b : a is the ratio of the electric field of the first sphere to that of the second sphere. The surface charge densities of the two spheres are given as As the charges are distributed uniformly over the surfaces of conducting.

Therefore, the surface charge densities are inversely related with the radii of the sphere. The surface charge density on the sharp and pointed ends of a conductor is higher than on its flatter portion since a flat portion may be taken as a spherical surface of large radius and a pointed portion as that of small radius.
