Question

The electrostatic potential on the surface of uniformly charged spherical shell of radius R = 10 cm is 120 V. The potential at the centre of shell, at a distance r = 5 cm from centre, and at a distance r = 15 cm from the centre of the shell respectively, are:

Select the correct option:

$40\;{\rm{V}},40\;{\rm{V}},80\;{\rm{V}}$

$0\;{\rm{V}},0\;{\rm{V}},80\;{\rm{V}}$

$0\;{\rm{V}},120\;{\rm{V}},40\;{\rm{V}}$

$120\;{\rm{V}},120\;{\rm{V}},80\;{\rm{V}}$
