A physics lab instructor is working on a new demonstration. She attaches two identical copper balls with mass m = 0.220 g to filaments of length L as shown in the figure. Both balls have the same charge of 6.80 nC, and are in static equilibrium when e = 5.20°. What is L (in m)? Assume the filaments are massless. m What If? The charge on both balls is increased until each filament makes an angle of e = 10.4° with the vertical. If both balls have the same electric charge, what is the charge (in nC) on each ball in this case? nC
