Homework Statement
Show that the average electric field within a spherical region, due to a single point charge, q at a distance r from the center, within the sphere is the same as the field at r due to a uniformly charged sphere with charge density p = -3q/4pi(R^3)
Homework Equations
The Attempt at a Solution
I can set up the integral for the average electric field, but run into problems when trying to evaluate it. I don't know whether there is a better way to tackle this problem, but i would appreciate any advice on how to tackle this problem.
This is a problem out of Griffiths Intro to Electrodynamics, problem 3.41
