What grade is this? I can't really say the answer cause I don't know it. Ask your Science teacher for extra help, like a tutor.

Recall that the force is
F = kqq/r^2
Without going into all the vector details, that means that the energy is
E = ∫ kqq/r^2 dr = -kqq/r
so plug in your numbers
F = kqq/r^2
Without going into all the vector details, that means that the energy is
E = ∫ kqq/r^2 dr = -kqq/r
so plug in your numbers
