Object A has mass 90.0 g and hangs from an insulated thread. When object B, which has a charge of + 130 nC, is held nearby, A is attracted to it. In equilibrium, A hangs at an angle q = 7.20 ° with respect to the vertical and is 5.00 cm to the left of B.
(a) What is the charge on A?
(b) What is the tension in the thread?
