Part A Consider a thin spherical shell centered on the proton, with radius r1r1 and infinitesimal thickness dr1dr1. 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 ρ(r1)ρ(r1) at this radius multiplied by the volume dVdV of the shell. What is dVdV in terms of r1r1? Express your answer in terms of the variables r1r1, dr1dr1, and any appropriate constants.
