Most materials tend to either lose electrons or gain electrons when rubbed. For example, rabbit fur tends to lose electrons when rubbed, while an acrylic (plastic) rod tends to gain electrons.The "triboelectric series" is a list that ranks various materials according to their tendency to gain or lose electrons.

 

Suppose an acrylic rod is rubbed with a piece of rabbit fur. If, before rubbing, the fur hadacharge of- 8.49C while the acrylic rod had a charge of 2.46C, andafterrubbing both fur and rod ended up with the same charge, how many electrons were transferred from the fur to the rod in the rubbing process?

 

Correct answer is 3.422e13 electrons. Show working out.
