Coulomb’s Law

Two stationary electric charges repel or attract each other with a force proportional to the product of the magnitude of charge and inversely proportional to the square of the distance between them ; ; For free space                      where C is the proportionality constant. The value of C depends upon the medium of the charges. […]
