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. In equilibrium each string makes an angle theta with vertical. Now, both the balls are immersed in a liquid. As a result the angle theta does not change. The density of the liquid is sigma . Find the dielectric constant of the liquid.

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)
