Need help with Charged objects and Electron Force (1 Viewer)

1. The problem statement, all variables and given/known data
A plate carries a charge of -3microC, while a rod carries a charge of +2microC. How many electrons must be transferred from the plate to the rod, so that both objects have the same charge?


2. Relevant equations
N= q/e


3. The attempt at a solution
I tried finding the amount of electrons and I stopped there, I really don't know how to go about with this problem.

Before worrying about electrons, how much charge (in microC) must be transferred from the plate?

1/2 microC's?

Let's see what happens in that case.

The -3 μC plate loses 0.5 μC, and so ends up with a charge of -3.5 μC.

The +2 μC rod gains +0.5 μC charge, ending up with 2.5 μC.

The final charges, -3.5 and +2.5 μC, are not equal. So no, it would not be 0.5 μC transferred.

The charges should be equal in magnitude and sign, (either both +, or both -) after the charge transfer.
 
wow thx
