Question

Two identical charged metal spheres (same charge q and mass), have the same density ρ and are suspended from an insulating string, repelling at an angle θ from the vertical. Now the balls are submerged in a liquid of density σ and the angle between them does not change. The new Coulomb force between the two charges because of the liquid in between is computed as 1/(4.π.ε) q2/(2.Lsin(9))2 where ε-eo-Ed Find ed of (the so-called relative permittivity of the liquid) p/20 p/σ p/(p-O) 2p/o
