Two pith balls, each with a mass of 1.3 g, are attached to non-conducting threads and suspended from a common hook. Each thread has a length of 10.8 cm. The balls are then given an identical charge, which causes them to separate. In equilibrium, the threads are separated by an angle of 8.1°. Calculate the charge on each pith ball, in coulombs (C).

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 1.3 g, are attached to non-conducting threads and
suspended from a common hook. Each thread has a length of 10.8 cm. The balls are
then given an identical charge, which causes them to separate. In equilibrium, the
threads are separated by an angle of 8.1°. Calculate the charge on each pith ball, in
coulombs (C).
