Two charges, qA and qB, are separated by a distance, d, and exert a force, F, on each other. Analyze Coulomb's law and answer the following questions.

What new force will exist if d is cut in half?
What new force will exist if qA is tripled and d is doubled?

2 answers

and your thinking is ...?
d would be 1/4 * F
qA and d would be 6 * F
