Charge is distributed throughout a spherical shell of inner radius r1 and outer radius r2 with a volume density given by ρ = ρ0 r1/r, where ρ0 is a constant. Determine the electric field due to this charge as a function of r, the distance from the center of the shell.

In this problem the volume charge density ρ is not uniform; it is a function of r (distance from the center.)
