A +2 uC and a +10 uC are 3cm apart
a) Find the electrostatic force between the charges
b) If the charges are brought together and touched, what would be the charge on each one?
c) These spheres are then moved 3 cm apart. What would be the force between them?

    What is the question on a) Coulombs law
    b) the charge equalizes IF the SPHERES are the same size. 6 microC each
    c. Again, Coulombs law.

    Notice you don't have to do much math on c). the difference between a and c is the numerator, in a) you have 20, and in c you have 36.
    So the force in c is 36/20 force in a.
