Ya sure I will get the MSC Physics (Classical Electrodynamics and Optics) exam paper issued by Karnataka State Open University so that you can prepare easily.

Here is the exam paper
1. (a) Define electromagnetic potentials. Express Maxwell’s equations in terms of the
electromagnetic potentials. (10)
(b) Show that the gauge transforms ' A and ' satisfy the Lorentz condition if and only if the gauge functions satisfy the wave equation. (5) OR

2. (a) Obtain an expression for Lienard-Wiechert potentials of a moving point charge. (10)
(b) Show that under Lorentz gauge E and B also satisfy the wave equation. (5)

3 .(a) Deduce the Abraham-Lorentz formula for radiation reaction and explain its
significance. (10)
(b) Show that the expression of power radiated by an oscillating electric dipole leads to
Larmor’s formula. (5)
OR

4 .(a) Derive expression for the power radiated by an oscillating electric dipole. (10)
(b) Write a note on Pinch effect. (5)

5. (a) Deduce an expression for Poynting vector and discuss the importance of Poynting theorem. (10)
(b) Starting from Fresnel’s equations obtain Brewster’s law.
