## Main Question or Discussion Point

I read in Corson and Lorrain that Gauss's law is more gneral than Coulomb's law.It can even be applied to moving charges whatever be their velocities/accelerations.Can anyone explain this?

The Lienard-Wiechert potentials have to be used.

Since div E=4pi rho in all cases, Gauss's law still applies.

However since the symmetry is lost, Gauss's law just gives the integral of E over a closed surface and can't be used to find E(r).
