How would I go about doing an experiment that would demonstrate Coulomb's law?
Thanks :D

What is with all the physics questions lately? School is out isn't it?
The magnitude of the electrostatic force between two point charges is directly proportional to the product of the magnitudes of each charge and inversely proportional to the square of the distance between the charges.

This is analogous to Newton's third law of motion in mechanics. The formula of Coulomb's law is of the same form as Newton's gravitational law: The electrical force of one body exerted on the second body is equal to the force exerted by the second body on the first.

Coulomb's law is the mathematical consequence of law of conservation of linear momentum in exchange by virtual photons in 3-dimensional space

Coulomb's law is analogous to the newtons law of gravitational forces which is F = G m1xm2/ d (square).

q plays the role of mass in coulomb's law. In gravitation the force is always attractive whereas in electricity there is attraction between unlike charges and repulsion between like charges. However in both situations, the forces decrease with the square of the distance between the objects and both forces act along a line between them.
