Question

Positive electric charge Q is distributed uniformly throughout the volume of an insulating sphere with radius R.From the expression for E=kQ/r2 for r>R and E=kQr/R3 for r<R, find the expression for the electric potential V as a function of r both inside and outside the uniformly charged sphere. Assume that V= 0 at infinity. Express your answer in terms of the given quantities and appropriate constants.

part a) V(r) r>R=
part b) V(r) r<R=
