Question: 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

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?

5.00 cm O130 nc A B
