A rubber rod and a fur cloth are initially uncharged. They are rubbed vigorously together for several seconds.
The rod and cloth are separated and the charge on each is measured. The rod is found to have negative charge.
If the charge on the rod is Q=−45 mC, how many electrons were transferred from the cloth to the rod.
(a)
5.08×1016 electrons
(b)
0.00 electrons
