Two identical ball with m = 0.1kg masses suspended in the air at one point on the non-conductive thin strands of equal length l = 1m. One of the balls was reported positive electric charge q = 1mkKl and given the opportunity to come into contact with another ball. After that, the balls separated by a distance r. Find r. The divergence angle of the balls considered small.
