A small sphere of mass m = 7.50g and charge q1 = 32.0nC is attached to the end of a string and hangs vertically as in Figure. A second charge of equal mass and charge q2 = -58.0nC is located below the first charge a distance d = 2.00cm below the first charge as in Figure. (a) Find the tension in the string. (b) If the string can withstand a maximum tension of 0.180N, what is the smallest value d can have before the string breaks?
