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?

**bobpursley**, Saturday, January 26, 2013 at 4:38pmWhat 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 dont 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.
