(a) A physics lab instructor is working on a new demonstration. She attaches two identical conducting globes with mass m = 0.180 g to cords of length L as shown in the figure. L. Both globes have the same charge of 6.80 nC, and are in static equilibrium when 0 = 5.05°, What is L (in m)? Assume the cords are massless. m (b) What If? The charge on both globes is increased until each cord makes an angle of 0 = 10.1° with the vertical. If both globes have the same electric charge, what is the charge (in nC) on each globe in this case? nc
