Two identical charged spheres are suspended by strings of equal lengths. The strings make an angle of 30° 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 1.6 gcm -3, the dielectric constant of the liquid is

Q. Two identical charged spheres are suspended by strings of equal lengths. The strings make an angle of $3 0^{\circ}$ with each other. When suspended in a liquid of density $0.8 g c m^{- 3}$ , the angle remains the same. If density of the material of the sphere is $1.6 g c m^{- 3}$ , the dielectric constant of the liquid is

Solution:

$K = \frac{d _{S}}{d _{s} - d _{l}} = \frac{1.6}{0.8} = 2$
