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.(adsbygoogle = window.adsbygoogle || []).push({});

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
