Question

Can the potential of a non-uniformly charged sphere be the same as that of a point charge?

Answer 1

Explanation:

Gauss' Law tells us that the electric field outside the sphere is the same as that from a point charge. This implies that outside the sphere the potential also looks like the potential from a point charge.If the sphere is a conductor we know the field inside the sphere is zero.
