How strong is the attractive force between a glass rod with a 0.700 x 10 -6 C charge and a silk cloth with a –0.600 x 10-6 C charge, which are 12.0 cm apart, using the approximation that they act like point charges?

If two equal charges each of 1 C each are separated in air by a distance of 1 km, what is the magnitude of the force acting between them? You will see that even at a distance as large as 1 km, the repulsive force is substantial because 1 C is a very significant amount of charge.

How far apart must two point charges of 75.0 x 10-9 C (typical of static electricity) be to have a force of 1.00 N between them?
