If the balls are far enough apart to behave more or less like equal point charges, then Fcoul should be given by Fcoul = kq2/R2. Write an equation that can be used to determine the amount of charge, q, on each ball as a function of m, R, and L as well and the gravitational and Coulomb constants, g and k. Show your derivation here.
