An uncharged conducting ball `B` lies inside a charged conductor `A` as shown in (Fig. 3.150). `B` is isolated from `A`.
.

A

When `B` touches the inner surface of `A`, then potential of `B` will change.

B

No net charge is inside the cavity.

C

There is an induced charge on `B`.

D

Potentials of `A and B` are same.

Text Solution

Verified by Experts

The correct Answer is:
b.,d.
potential everywhere inside a charged conductor is same. Even if we touch A and B, nothing will happen because potential is same prior to touching.
