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?
3 answers
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.
A small cork with an excess charge of +5.0 μC
is placed 0.12 m from another cork, which
carries a charge of −3.2 μC.
What is the magnitude of the electric force
between the corks? The Coulomb constant is
8.98755 × 109 N · m2/C2.
Answer in units of N.
