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 g /cm3, the angle remains the same. If density of the marterial of the sphere is 1.6 g /cm3, then dielectric constant of the liquid is

Two identical charged spheres are suspended by strings of equal length

1.	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 g /cm3, the angle remains the same. If density of the marterial of the sphere is 1.6 g /cm3, then dielectric constant of the liquid is
Answer» 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 $0.8 {g /cm}^{3}$ , the angle remains the same. If density of the marterial of the sphere is $1.6 {g /cm}^{3}$ , then dielectric constant of the liquid is
