Potential Energy of a Finite Proton

[Interdimensional]

Homework Statement

This was in a problem set I found. Suppose that the proton in a hydrogen atom is not a pointlike object, but instead described by a uniform spherical charge distribution with charge e and radius R = 8.7 x 10^-16 m. Using Gauss's law and the definition for the electric potential, derive an expression for the potential energy of this finite sized proton.
