(a) A physics lab instructor is working on a new demonstration. She attaches two identical copper globes with mass m= 0.220 g to strings of length L as shown in the figure. A Both globes have the same charge of 7.60 nC, and are in static equilibrium when @ 5.25", What is L (in m)? Assume the strings are massless. (b) What If? The charge on both globes is increased until each string makes an angle of -10.5 with the vertical. If both globes have the same electric charge, what is the charge (in nC) on each globe in this case) nC
