Consider the following very rough model of a beryllium atom. The nucleus has four protons and four neutrons confined to a small volume of radius $10^{-15}m$. The two $1s$ electrons make a spherical charge cloud at an average distance of $1.3 \times 10^{-11}m$ from the nucleus, whereas the two $2s$ electrons make another spherical cloud at an average distance of $5.2 \times 10^{-11}m$ from the nucleus. Find the electric field at:
  1. A point just inside the $1s$ cloud.
  2. A point just inside the $2s$ cloud.
Write four properties of $\gamma$-rays. What will be the difference between velocity of $\gamma$-ray of wavelength 0.01 Å and X-ray of wave-length 3 Å.
  1. Obtain an expression for the mutual inductance between a long straight wire and a square loop of side a as shown in Fig.
  2. Now assume that the straight wire carries a current of $50A$ and the loop is moved to the right with a constant velocity $, v = 10\ m/s.$ Calculate the induced emf in the loop at the instant when $x = 0.2\ m$. Take $a = 0.1\ m$ and assume that the loop has a large resistance.
In en experiment on photoelectric effect, light of wavelength $400$ run is incident on a cesium plate at the rate of $5.0W.$ The potential of the collector plate is made sufficiently positive with respect to the emitter so that the current reaches its saturation value. Assuming that on the average one out of every $10^\circ$ photons is able to eject a photoelectron, find the photocurrent in the circuit.
When a dielectric is placed in an electric field, it gets polarized. The electric field in a polarized material is less than the applied field. When a paramagnetic substance is kept in a magnetic field, the field in the substance is more than the applied field. Explain the reason of this opposite behaviour.
