Two pith balls, each with a mass of 5.00 g, are attached to non-conducting threads and suspended from the same point on the celling. Each thread has a length of 1.00 m. The balls are then given an identical charge, which causes them to separate. At the point that the elctric and gravitational forces balance, the threads are separated by an angle of 30.0°. Calculate the charge of each pith ball.

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 pith balls, each with a mass of 5.00 g, are
attached to non-conducting threads and
suspended from the same point on the celling.
Each thread has a length of 1.00 m. The balls are
then given an identical charge, which causes them
to separate. At the point that the elctric and
gravitational forces balance, the threads are
separated by an angle of 30.0°. Calculate the
charge of each pith ball.
