Question
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 - 3Q, the new potential difference between the same two surfaces is :
Options
A.V
B.2V
C.4V
D.-2V
Solution
The potential difference (work done against field) between the shell & sphere is due to the field present inside that region which is only due to the sphere.
