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. The spheres are given the same electric charge, and the two come to equilibrium when each string is at an angle of 0 = 6.00° with the vertical. If each string is L = 1.00 m long, what is the magnitude q of the charge on each sphere? C
