based on Coulomb's law in a vacuum, where F is the magnitude of the force between two particles with electric charges Q1 and Q2 respectively, placed at a distance r apart

Note 1 to entry: In a vacuum, the product of the electric constant ε0 and the electric field strength E is equal to the electric flux density D:

D = ε0E

Note 2 to entry: The electric constant ε0 is related to the magnetic constant μ0 and to the speed of light in vacuum c0 by the relation ε0μ0c02 = 1.

Note 3 to entry: The value of the electric constant ε0 is equal to

fondée sur la loi de Coulomb dans le vide, où F est la norme de la force s'exerçant entre deux particules de charges électriques Q1 et Q2 respectivement, placées à une distance r l'une de l'autre

Note 1 à l'article: Dans le vide, le produit de la constante électrique ε0 par le champ électrique E est égal à l'induction électrique D:

D = ε0E

Note 2 à l'article: La constante électrique ε0 est liée à la constante magnétique μ0 et à la vitesse de la lumière dans le vide c0 par la relation ε0μ0c02 = 1.

Note 3 à l'article: La valeur de la constante électrique est égale à
