A hollow conducting sphere of inner radius r and outer radius 2R is given charge Q as shown in figure, then the

A

potential at A and B is same.

B

potential at O and B is same.

C

potential at O and C is same.

D

potential at A,B,C and O is same.

Text Solution

Verified by Experts

The correct Answer is:
A, B, C, D
a.,b.,c.,d.
points `A` and `B` lie within the same metal hence `V_(A)=V_(B)`. The potential inside a hollow sphere is same as potential at the surface, hence `V_(A)=V_(B)=V_(C)=V_(0)`.
