Electrostatics - Write an expression for the volume charge density
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)
PDF and Word document attached show how to give an expression for charge density at a point and other questions.
