Two small metallic spheres, each of mass m=0.2 g, are suspended as pendulums by light strings of length "L" as shown in the figure. 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° with the vertical. How long are the strings ?
