HW 2-6 Two small metallic spheres, each of mass m = 0.200 g, are suspended as pendulums by light strings of length L as shown in Figure 2-14. The spheres are given the same electric charge of 7.2 nC, and they come to equilibrium when each string is at an angle of 0 = 5.00° with the vertical. How long are the strings?
