Two small plastic balls hang from threads of negligible mass. Each ball has a mass of 0.14 g and a charge of magnitude q. The balls are attracted to each other. When in equilibrium, the balls are separated by a distance of 2.05 cm and the threads attached to the balls make an angle of 20 degrees with the vertical.(a) Find the magnitude of the electric force acting on each ball.(b) Find the tension in each of the threads.(c) Find the magnitude of the charge on the balls.
