there is a +q and -q on the x-axis. the +q is L/2 in the negative direction and the -q is L/2 in the positive directions. the distance between the two charges is L. there is a test charge P on the y axis a distance r from both charges.(adsbygoogle = window.adsbygoogle || []).push({});

we had to find the electric energy stored in the dipole.

she gave us the answer -> W= (q^2)/(4*pi*epsilon_0*L) => W=(q_1*q_2)/(4*pi*r_12)

i do not understand how she got this. could someone please enlighten me a little bit?

thanks
