Why is the electric field from a dipole nonzero? Intuitively, I know there are electric field lines going from the positive to negative charge, so there should be an electric field. But if I apply Gauss's law, then the enclosed charge should be zero (as the positive and negative charges cancel),...
It pains me to break this thread by fixing the issue, but here we are. :) We are now inserting \begingroup and \endgroup directives into post and comment bodies, so all command definitions should be scoped to individual posts. For now, I'm only enabling this on Math (and here on meta), but barr...
