A small sphere of mass m = 6.80 g and charge q = 28.1 nC is attached to the end of a string and hangs vertically as in the figure. A second charge of equal mass and charge 92 = -58.0 nC is located below the first charge a distance d = 2.00 cm below the first charge as in the figure. 91 92 (a) Find the tension in the string. .103 N (b) If the string can withstand a maximum tension of 0.180 N, what is the smallest value d can have before the string breaks? 9027 X Your response differs from the correct answer by more than 10%.
