Questions  

A solid conducting sphere having a charge 'Q' is surrounded by an uncharged concentric conducting hollow spherical shell. Let the P.D 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 5Q. The new PD between the same two surfaces is

a
V
b
2V
c
4V
d
-2V

detailed solution

Correct option is A

P.D does not changes.As    dV does not depend on the charge present on outer sphere.
