Dirac delta function problem
Not what you're looking for?
(a) Write an expression for the electric charge density p (r) of a point charge q at r/. Make
sure that the volume integral of p equals q.
(b) What is the charge density of an electric dipole, consisting of a point charge -q at the
origin and a point charge +q at a?
(c) What is the charge density of a uniform, infinitesimally thin spherical shell of radius R and
total charge Q, centered at the origin? [Beware: the integral over all space must equal Q.]
