Two identical...

Question

Two identical charged particles are suspended in air by strings of equal length. The strings make an angle of $30^{\circ}$ with each other. When suspended in a liquid of density 0.4g/cc the angle remains the same. The dielectric constant of the liquid is (given the density of the metal sphere is 0.8g/cc)
