Problem 2.

(a) Find the electric potential inside (r<R) and outside (r>R) a uniformly charged solid sphere (with the charge density roe) whose radius is R and whose total charge is Q. Use infinity as your reference point. Plot schematically V(r) as a function of r.

(b) [15%] By using the result for the electric potential in the previous part, calculate the electric field in each region (r>R and r<R)
