The electrostatic potential on the surface of uniformly charged spherical shell of radius 
is 120 V. The potential at the centre of shell, at a distance 
from center, and at a distance 
from the centre of the shell respectively, are:
Text Solution
Verified by ExpertsB
The potential inside a uniformly charged spherical shell is equal to the potential on its surface. This means:
This maintains the potential at both the center of the shell and any point inside it up to the surface. Therefore, the potential at the center of the shell and at any point inside the shell (like at a distance 
) is also 120 V.
For a point outside the shell, at a distance 
, the potential is given by the formula:
