hang in equilibrium as shown in fig. the ligth of each string is l
Two identical balls each having a density ρ 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 θ with vertical. Now, both the balls are immersed in a liquid. As a result the angle θ does not change. The density of the liquid is σ . Find the dielectric constant of the liquid.
