The figure below shows a small, hollow, plastic ball hanging vertically from a thin, lightweight thread. The ball has a mass of 6.60 g and a uniformly distributed charge of 91 = 32.9 nC. Directly below it is a second ball with the same mass, but a charge of 92 = -58.0 nC. (Assume this second ball is fixed in place.) The centers of the two plastic balls are a distance d = 2.00 cm apart. 91 92 (a) What is the tension (in N) in the thread? 0.0466 X Draw a free body diagram showing all the forces acting on the hanging ball. What are the directions of the forces? Use this diagram and Newton's 2nd law to find the tension. What is the magnitude of the electric force? Be careful with unit conversions. N Need Help? (b) The thread will break if the tension in it exceeds 0.180 N. What is the smallest possible value of d (in cm) before the thread breaks? cm
