An object carries a charge of -8.0 ìC, while another carries a charge of -2.0 ìC. 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= -5ìC
Object 2- Qavg = 3ìC
3E-6 C/1.6E-19 C = 1.875E13 electrons

Did I do this right?

Those "i" things before the "C" were supposed to be micro for microcoulombs

(-2.0 μC+Ne = -8.0 μC-Ne)
2Ne= 6E-6
Ne= 3E-6
N= q/e =3E-6/1.6E-19
N= 1.9E13 electrons
