2 small spheres each of mass m and carrying +q coulomb, are suspended by massles insulating threads, each of length l. Prove that `q^(2)=(4mgl^(2) sin^(2) theta tan theta )4 pi epsilon_(0)`, where `theta` is angle made of strings with the vertical at equilibrium.

Two tiny spheres each having mass mkg and charge q coulomb are suspended from a point by insulating threads each l metre long but negligible theta with the vertical. Prove that, q^(2)=(4mgl^(2)sin^(2)theta tan theta)4pi epsilon_(0)

Two small spheres each of mass 'm' kg and charge q coulomb are suspended from a point by insulating threads each of 1 metre length, but of negliglible mass. If theta is the angle which each string makes with the verticle vertical when equilbrium has been reached, show that q^(2) = 4mg l^(2) sin^(2) theta tan theta (4pi in_(0))

Two small spheres each having mass m kg and charge q coulomb are suspended from a point by insultaing threads each l metre long but of negligible mass. If theta is the angle, each string makes with the vertical when equilibrium has been attained show that q^2 = (4m g l^2 sin ^2 theta tan theta) 4 pi upsilon_0
