total charge of 6.63E-6 C distributed on 2 metal spheres. When the spheres are 6 cm apart, they each feel a repulsive force of 26.9 N. How much charge is on each sphere?? I know that F=(k x q1 x q2)/(r x r) Im not exactly how to solve for these when i dont know either one of them to solve for one another. How should i go about this??
