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))`
