a small cork with a excess charge of +6.0 μC
(1 μc = 10^-6 C) is placed 0.12 m from another cork, which carries a charge of -4.3 μC....

how many electrons are on the negative cork?

  • physicss -

    divide the charge by the charge on one electron. This does not change. The information on the positive cork, and distance, is a distractor, ignore it.
