Question

Two small spheres each have a mass m of 0.100 g and are suspended as pendulums by light insulating strings from a common point, as shown in the figure below. The spheres are given the same electric charge, and the two come to equilibrium when each string is at an angle of θθ= 3.00∘∘; with the vertical.

1)

If each string is 1.00 m long, what is the magnitude of the charge on each sphere? (Express your answer to three significant figures.)

Answer 1

It is based equilibrium of system of point charges and Coulomb's inverse square law of electrostatics.

This problem is also solved by using Lami's theorem.
