A small sphere of mass m = 7.60 g and charge q, = 31.9 nc is attached to the end of a string and hangs vertically as in the figure. A second charge of equal mass and charge q, = -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. 49048 X Your response differs from the correct answer by more than 10%. Double check your calculations. 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? X Your response differs from the correct answer by more than 100%. cm
