Question

(a) A physics lab instructor is working on a new demonstration. She attaches two identical copper globes with mass $m = 0.210$ g to filaments of length $L$ as shown in the figure. Both globes have the same charge of 6.40 nC, and are in static equilibrium when $\theta = 4.50^\circ$. What is $L$ (in m)? Assume the filaments are massless. m (b) What If? The charge on both globes is increased until each filament makes an angle of $\theta = 9.00^\circ$ with the vertical. If both globes have the same electric charge, what is the charge (in nC) on each globe in this case? nC
