A solid conducting sphere having a charge
is surrounded by an uncharged concentric conducting hollow spherical shell. Let the potential difference between the surface of solid sphere and that of the outer surface of hollow shell be
. What will be the new potential difference between the same two surfaces, if the shell is given a charge
?

In charged conducting sphere,

In spherical shell,

where,
and
are the radii of sphere and spherical shell, respectively.
Potential at their surfaces,

When the shell is given a charge
the potential at its surface and also inside will get charged by a potential
