Small identical balls with equal charge are fixed at the vertices of a reggular hexagon after of N sides ,each of length a At a certain instant one of the ball is releases and after a sufficiently long time the adjacent ball is released .The kinetic energies of the two releases balls differ by k at a sufficenlty long distance from the polygon . Determine the charge on each ball.
