Assertion : Two identical balls are charged by q. They are suspended from a common point by two insulating threads l each. In equilibrium, the angle between the tension in the threads is 180^(@) . (Ignore gravity). Reason : In equilibrium tension in the spring is T=1/(4pi epsi_(0)) (q.q)/l^(2)

Two identical balls each having a density rho are suspended from as common point by two insulating strings of equal length. Both the balls have equal mass and charge.
