An object carries a charge of -8.0 uC, while another carries a charge of -2.0 uC. How many electrons must be transferred from the first object to the second so that both objects have the same charge?

Qavg = (object 1 + object 2)/2
Qavg= -5uC
Object 2- Qavg = 3uC
3E-6 C/1.6E-19 C = 1.875E13 electrons
