Asked by Luke Skywalker
A small cork with an 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.
a. What is the magnitude of the electric force between the corks?
b. Is this force attractive or repulsive?
c. How many excess electrons are on the negative cork?
d. How many electrons has the positive cork lost?
Please explain it. I want the answer, but I also want to understand it. Thank you!

opposite charges, they attract.
Use coulombs law to find the force.
c. excells= chargeonCork/chargeononeElectron
