I am very confused on this homework question. I do not even know to where to begin. It is the only one I could not answer. Please help me solve it!!
A ball of charge +2q is placed on the x-axis at x = -2a. A second ball of charge -q is placed nearby so that the net electric potential at the origin because of the two balls is -8.00 kq/a. At what distance from the origin is the second ball?
Thanks!
