Question

The radius of a conducting spherical shell is 10 mm and a 100 mC charge is spread on it. The force acting on a 10 mC charge placed at its centre is .......

Answer 1

The net force experienced by the charge at the center will be zero.

Explanation:

Since the charges spread over the surface of a metal uniformly so in case of a conducting spherical shell having some amount of charge on it will distribute the charge uniformly over the surface of the sphere and will exert a radial force on the charge placed at its center from all the directions in a symmetric manner.

Therefore the net force experienced by the charge at the center will be zero.
