Consider a spherical charge distribution which has a constant density p from r = 0 out tor = a and is zero beyond. Find the electric field for all values of r, both less than and greater than a. Is there a discontinuous change in the field as we pass the surface of the charge distribution at r = a? Is there a discontinuous change at r = 0?
