Two balls with diameters d1 = 0.20 m and d2 = 0.80 m are in a vessel with kerosene at a distance l = 160 cm (Fig.). The first ball is charged to a potential f1 = 250 V, the second - to a potential f2 = -100 V. The balls are connected by a conductor, which is then removed. Find the intensity and potential of the electric field at the point located midway between the centers of the balls. Relative dielectric constant of kerosene e = 2.
