Question:

A point charge of +5 nC is located at the origin. This charge is surrounded by a spherically symmetric negative charge distribution with volume density ρ(r) = Ce–r/a.

(a) Find the constant C in terms of a if the total charge of the system is zero.

(b) What is the electric field at r = a?
