where F12 is the force exerted on the particle with electric charge Q1 by the particle with electric charge Q2 , k a positive constant, r21 the vector from the particle with electric charge Q2 to the particle with electric charge Q1, r = |r21| the distance between particles and e21 the unit vector r21/r

Note – In vacuum the constant k is equal to 1/4πε0 where ε0 is the electric constant.

F12 est la force exercée sur la particule de charge électrique Q1 par la particule de charge électrique Q2, k une constante positive, r21 le vecteur issu de la particule de charge électrique Q2 et aboutissant à la particule de charge électrique Q1, r = |r21| la distance entre particules et e21 le vecteur unitaire r21/r

Note – Dans le vide la constante k est égale à 1/4πε0ε0 est la constante électrique.
