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.
