A solid conducting sphere having a charge Q is surrounded by an uncharged concentric conducting hollow spherical shell. Let the potential difference between the surface of the solid sphere and that of the outer surface of the hollow shell be V. If the shell is now given a charge of `-3 Q`, then the new potential difference between the same two surface is

A

V

B

2V

C

4V

D

`-2V`

Text Solution

Verified by Experts

The correct Answer is:
A

In such situation potential difference depends only on the charge on inner sphere. Since, charge on inner sphere is unchanged Therefore, potential difference V will remain unchanged.
