about coulumb law

Coulombs’ law describes an inverse square law of an electrostatic force. (http://en.wikipedia.org/wiki/Coulomb%27s_law)
F=e(Q1xQ2)/R^2 where e is a constant
Q1 and Q2 are electrical charges
R – is the distance between these charges
The law was formulated and demonstrated by a French physicist Charles Augustin Coulomb (1736 – 1806). http://en.wikipedia.org/wiki/Charles-Augustin_de_Coulomb
Before Coulombs the attraction of dislike charges and repulsion of like charges was well know, however he was the first to formulate the law and to quantitatively demonstrate the force.
I hope it was useful

Coulomb's law tells you the force between two electrical charged bodies. Monsieur Coulomb found that the force is proportional to each of the two charges and inverse proportional to the square of the distance of the two charges.
Later James Clerc Maxwell showed Coulomb's law is a result of a more general principle: the first law of Maxwell.
It is very important inside an atom.

Mr. Coulomb, I think
I forgot what it is, somesort of electrical magnetism maybe. Look it up.
