Coulomb's Law
Main Concept
|
Coulomb's inverse square law, is a law of physics that describes the electrostatic interaction between two electrically charged particles.
The law states that:
|
where
|
is a proportionality constant approximately equal to  ,
and are the charges of the two particles,
is the distance between the two particles.
|
|
|
If the force is positive the particles are being repulsed. If the force is negative, the particles are being attracted.
|
|
|
Adjust the sliders to change the charge and distance of each particle.
