Solved: Two small metallic spheres, each of mass 0.20 g,
Chapter 15, Problem 15.44(choose chapter or problem)
Two small metallic spheres, each of mass 0.20 g, are suspended as pendulums by light strings from a common point as shown in Figure P15.15. The spheres are given the same electric charge, and it is found that they come to equilibrium when each string is at an angle of 5.0 with the vertical. If each string is 30.0 cm long, what is the magnitude of the charge on each sphere?
