Question

A 33 uC point charge is at the center of a hollow ungrounded thin metallic spherical shell. The shell has a net charge of + 4.0 uC . Calculate the electric charge on the inner and outer surface of the shell.

Answer 1

Answer:

Explanation:

The charge at the centre that is 33 uC will induce -33 uC on the inner surface and + 33 uC charge on the outer surface of the shell. Since the shell has a net charge of +4 uC,the outer surface must have +37 uC so the shell have net charge of + 4uC .

outer surface +37 uC

inner surface -33 uC

net charge on the shell = +4uC
