9 TWO small spheres each have a mass m of 0.100 g and are suspended as pendulums by light insulating strings from a F common point, as shown in the gure. The spheres are given E the same electric charge, and the two come to equilibrium ; whim each string is at an angle of 9 = 7600\" with the vertical! ' If each string is L = 1.00 m long, what is the magnitude q of the charge on each sphere
