Electric Charges and Fields

One of the fundamental properties is the electromagnetic property. Charge cannot be destroyed by any process and this contributes formally to the law of charge conservation.

Question

Two small balls, each of mass 3.0 g, are attached to silk threads 30 cm long, which are in turn tied to the same
point on the ceiling, as shown in the figure. When the balls are given the same charge Q, the threads hang at
0 = 3.0° to the vertical.
What is the magnitude of Q?
