Calculate the magnitude of the force, due to an electric dipole moment 3.76e-29 C.m, on an electron 2.23e-8 m from the center of the dipole, along the dipole axis. Assume that this distance is large relative to the dipole's charge separation.

Ok, i have a feeling this is a really easy problem, but i've like gone retarded and i can't do any physics it seems right now. So, first problem, i didn't understand what the center of the dipole was or the dipole axis. as in, halfway between the two charges, or when they're lined up the line that connects them, extended. I tried both to no avail... probably cause i wasn't sure what to do from there either. I tried just Kq/r^2, but i didn't know q, so i tried solving for q, but i know i did that wrong, because my equations weren't right. which i decided didn't matter cause i figured i was doing it wrong and that i should binomial expansion. But i realized i didn't actually understand how i was supposed to use it. So, i'm just stuck, i have no idea how to even start right. So some guidance in the right direction would be great, thanks....
