A conductor with a positive Q (charge) of 4C has 12.56 x 1018 electrons added to it. It will have a Q =

  • 6.
  • 2.
  • 0.

Explanation from PART66Online

Each electron carries about 1.6 x 10^-19 coulombs, so 12.56 x 10^18 electrons add roughly 2 C of negative charge. Subtracting this from the original positive charge of 4 C leaves a net charge of about +2 C on the conductor.

Charge of one coulomb equals 6.28 * 1018. So that means what you have added 2 coulombs. Total will be 6.

If you have a positive Q, and you add electrons, wont it be 4C - 2C?
