A) Write an expression for the volume charge density, rho(r) of a point charge q at r'

(the volume integral of rho(r) = q)

b) What is the volume charge density of an electric dipole consisting of a point charge-q at the origin and a point charge +q at a(bar)

c) What is the charge density of a uniform infinitesimally thin spherical shell shell of Radius R and total charge Q which is centered at the origin.
note: the integral over all space must equal Q)
