Q.Two small metallic spheres, each of mass 0.20 g, are suspended as pendulums by light strings from a common point . 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?
