Hint: the electric field for a uniformly charged sphere is
E=Qr
4π0R3ˆ
rfor r < R, E=Q
4π0r2ˆ
rfor r > R
where Ris the radius of the sphere and Qis the total charge. You don’t need this
electric field, but you will need to evaluate an integral that is the same the Ecalculation
for a uniformly charged sphere, so these results can save you doing the integral.
