Question

There are 2 point charges. Q1 is 4nC and is at (-2,0). Q2 is -2nC and is at (0,3).

How much work does the electric field do when a third point charge of +3.00 nC is moved from infinitely far away and placed at the origin?

I know infinitely far means Va will be 0. However because there are 2 other charges instead of 1, I do not know how to manipulate k(Q)/d to fit all the charges in. Help!

Energy doesn't care about direction. Just sum the two. kq3q1/r + kq3q2/r.
