Two identical balls each having a density 1.6 gcm –3 are suspended from a common point by two insulating strings of equal length. Both the balls have equal mass and charge. In equilibrium each string makes an angle 30° with vertical. Now both the balls are immersed in a liquid of density 0.8 gcm –3 , but the angle does not change. The dielectric constant of the liquid is-
