3 small spheres of mass m are suspended by the threads of negligible masses and length l from a common point. A charge Q is divided equally between the sphere and they come to equilibrium at the corner of the horizontal equilateral triangle whose sides are d. show that
Q*Q= 12 ∏ є mg d*d*d [(l*l)-(d*d/3)]^ -1/2
