Four identical metallic objects carry the following charges: +4.2 µC, +5.4 µC, -2.2 µC, and -4.4 µC. The objects are brought simultaneously into contact, so that each touches the others. Then they are separated.
How many electrons (or protons) make up the final charge on each object?

• physics -

The total charge is 9.6-6.6 = +3.0 uC

Each object gets 1/4 of that after they are contacted and separated.

Divide by the electron charge, e, for the number of excess protons on each object.
