Two balls of same radius and weight are suspended on threads so that their surfaces are in contact A total charge of Q 4 x 10 7C is given to the balls makes them repel each other to an angle of 60 The angle of divergence becomes 54 when balls are immersed in kerosene Find the density s of the material of the balls if the distance from the point of suspension to the centre of the ball is 0 2 m Density of kerosene o 800 kg m dielectric constant k 2 tan 27 0 5
