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.

Find the dielectric constant of the liquid.

and the angle made by any string with the vertical is θ . Find the magnitude of the charge on each sphere. each having a mass m hang in equilibrium as shown in fig. the ligth of each string is l Two identical small charged spheres
