Two identical charged spheres are suspended by strings of equal lengths. The strings make an angle of $30^{\circ}$ with each other. When suspended in a liquid of density $0.8\; gcm^{–3}$, the angle remains the same. If density of the material of the sphere is $16 g cm^{–3},$ the dielectric constant of the liquid is
