    Have a problem that I'm not sure how to approach any help would be appreciated!

    If the electrostatic force between two protons is equal to 1x10^-7 Newtons, what is the distance between them?

    F = kq1q2/r^2

    Given F, and k, q1 = q2 = a constant you have to look up, you can find r...

    r = sqrt(kq1q2/F)
