Two 3 kg spherical masses are connected by a 20 m long thread of negligible mass that does not stretch. The masses are charged so they have the same amount of negative charge and the system is hung from the ceiling by the center of the thread.
Determine the charge of each sphere if the angle between the suspended sides of the thread is 17 degree.
