The figure below shows a small hollow rubber ball hanging vertically from a thin lightweight string The ball has a mass of 7 00 g and a uniformly distributed charge of q 30 2 nC Directly below it is a second ball with the same mass but a charge of q2 58 0 nC Assume this second ball is fixed in place The centers of the two rubber balls are a distance d 2 00 cm apart 91 92 a What is the tension in N in the string N b The string will break if the tension in it exceeds 0 180 N What is the smallest possible value of d in cm before the string breaks cm
