Coulomb's law, or Coulomb's inverse-square law, is a law of physics that describes force interacting between static electrically chargedparticles. In its scalar form, the law is:
{\displaystyle F=k_{e}{\frac {q_{1}q_{2}}{r^{2}}}},
where ke is Coulomb's constant (ke = 8.9875×109 N m2 C−2), q1 and q2 are the signed magnitudes of the charges, and the scalar r is the distance between the charges. The force of the interaction between the charges is attractive if the charges have opposite signs (i.e., F is negative) and repulsive if like-signed (i.e., F is positive).
The law was first published in 1784 by French physicist Charles-Augustin de Coulomb and was essential to the development of the theory of electromagnetism. Being an inverse-square law, it is analogous to Isaac Newton's inverse-square law of universal gravitation. Coulomb's law can be used to derive Gauss's law, and vice versa. The law has been tested extensively, and all observations have upheld the law's principle.

According to. Coulombs law if two. Charges are at a distance of r then the force between them is
F=kq1q2/r²
where k is proportionality constant
k=1/4πepsilan0
F=kq1q2/r²
where k is proportionality constant
k=1/4πepsilan0
