Suppose a vector field V is represented as (2xz+3y²)ĵ + 4yz² k. Check
the Stoke's Theorem on the square surface of unit length drawn in the
YZ- plane.
A plane electro-magnetic wave is crossing through a material constructed
from a metal. Derive an expression for the distance after which the

The space between the plates of the parallel plate capacitor is filled with
two slabs of linear dielectric material. Each slab has the thickness a so
that the total distance between the plates is 2a. The first slab has the value
of dielectric constant as 2 and the second slab has dielectric constant as
1.5. The free charge density on the top surface is o and on the bottom
surface is -o. Find out the value of polarization on each slab. Also find
out the potential difference between the plates along with the location and
amount of all bound charges.
