Task id16497
A ball of mass m = 0.5 kg is suspended from a thread and is given a charge q = 0.1 µC. When a ball of diameter d = 5 cm, charged with the same charge, was brought to it from below, the tension force of the suspension decreased threefold. Find the distance between the centers of the balls and the surface density of the electric charge on the balls.
