Consider a thin spherical shell centered on the proton, with radius r1 and infinitesimal thickness dr1. Since the shell is so thin, every point within the shell is at essentially the same radius from the proton. Hence the amount of electron charge within this shell is equal to the electron charge density rho(r1) at this radius multiplied by the volume dV of the shell. What is dV in terms of r1?
