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:
F = ke q1q2r2
where
ke is a proportionality constant approximately equal to 8.987551 x109 N⋅m2 C2 ,
q1and q2 are the charges of the two particles,
r 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.
q1= ×10−5 C
q2= ×10−5 C
r= m
F =
