A hollow metal sphere of radius $5 \mathrm{~cm}$ is charged such that the potential on its surface is $10 \mathrm{~V}$. The potential at a distance of $2 \mathrm{~cm}$ from the centre of the sphere is
zero
$10 \mathrm{~V}$
$4 \mathrm{~V}$
$10 / 3 \mathrm{~V}$
Solution
Potential at any point inside the sphere $=$ potential at the surface of the sphere $=10 \mathrm{~V}$.
