Two identical charged spheres are suspended in air from a ceiling using strings of equal length. The point of suspension is common to both the spheres. Neglect the density of air. The density of material of spheres is 2 "g/cm"^3.Both spheres repel each other and the strings are inclined at a certain angle with the vertical when the system is in equilibrium. Now both the sphere are dipped into a liquid of specific gravity 1 and dielectric constant K, but angle that the strings are making with the vertical remains unchanged. Let T_1 be the tension in both the strings when the spheres are in air and T_2, be the tension in strings when spores are dipped in liquid. Let F_1 be the electrostatic force between charges when they were kept in air and F_2, be the electrostatic force when spheres are dipped in liquid. The magnitude of F_2//F_1 is |
