If the space between the plates of a capacitor is filled will a dielectric material, does
it affect the value of capacitance? Justify your answer.

b) State and explain the boundary condition for the displacement vector D at the
boundary separating two dielectric media.

A positive 20µC charge is placed at the centre of a circle of radius 20 cm. If we
move a positive 2µC charge once along the circumference of the circle, will any
work be done in the process? Justify your answer.
