Question: a plate carries a charge of -3.0 uC, while a rod carries a charge of +2.0 uC. How many electrons must be transferred from the plate to the rod, so that both objects have the same charge?
The Attempt at a Solution
N= q/e = -2.0e-6/-1.6e-19 = 1.25e13 electrons transferred
something doesn't seem right about this problem. the prof didnt mark this wrong, but he marked -2.0e-6 C wrong? anyone with the fix?
