Asked by solexgirl12
"Two small spheres are located 0.50m apart. Both have the same charge on them. If the repulsive force is 5.0N, what charge is on the spheres, in microcoulombs?"
I can begin to use my electrical force formula, but then I have two unknown charges. The anwser is 12 uC, but I am getting numbers like 3.98 x 10 to the -10. Can anyone help please?

5=9E9 q^2/.5^2
q= sqrt 1.39E-10 = 12microC
q= sqrt 1.39E-10 = 12microC
