Question

Use Gauss' law to obtain the expression for the electric field due to a uniformly charged infinite plane sheet.

A cube of side L is kept in space, as shown in the figure. An electric field E = (Ax + B) î N/C exists in the region. Find the net charge enclosed by the cube.

Define electric potential at a point and write its SI unit.

Two capacitors are connected in series. Derive an expression of the equivalent capacitance of the combination.

Two point charges + q and − q are located at points (3a, 0) and (0, 4a) respectively in x-y plane. A third charge Q is kept at the origin. Find the value of Q, in terms of q and a, so that the electrostatic potential energy of the system is zero.
