Okay so say we have charge Q on a 2-sphere of radius R then the charge distribution will be rho=(Q/2piR^2)delta(r-R), which gives Q when integrated over space.
1) So my question is, what does this say about rho? To me, it says that rho is zero everywhere except on the surface of the sphere where it is infinite.
P.S. yes I know the delta function is really a distribution. What I'm asking for is a Physicist's interpretation of the charge density.
Thanks,
kevin
