Deriving an equation

  1. Nov 19, 2006 #1
    Two identical small charged spheres, each having a mass of m, hang in equilibrium as shown below. If the length of each spring is L and the angle 0 (theda), find the expression for the magnitude of the charge on each sphere, assuming the spheres have identical charges in terms of m, g, k, L, and 0.

    It's using Coulomb's Law and I understand the basis of the question and how to figure it out, but I don't know which equations are available to use.
