Hi all, I'm kind of confused right now about some concepts. - Dipoles are essentially point charges of the same magnitude but different signs that are a certain distance away from each other, right? -In my textbook, they were calculating a charged particle that is on the dipole axis. They got an a E that is in the direction of z (as opposed to x/y). Why is the direction of the electric field at the point P (on the dipole axis) z? The charges of the dipole and the charge at P are all on x, y plane, unless I misunderstood something. -However, in earlier examples with charges on the same plane with other charges, the E they got was restricted in the x,y plane. Why is this so? Am I missing something? Thanks in advance!
