Ello dear :)
Coulomb's law, or Coulomb's inverse-square law, is an experimental law[1] of physics that quantifies the amount of force between two stationary, electrically charged particles. The electric force between charged bodies at rest is conventionally called electrostatic force[2] or Coulomb force.[3] The quantity of electrostatic force between stationary charges is always described by Coulomb's law.[4] The law was first published in 1785 by French physicist Charles-Augustin de Coulomb, and was essential to the development of the theory of electromagnetism, maybe even its starting point,[5] because it was now possible to discuss quantity of electric charge in a meaningful way.[6]
In its scalar form, the law is:
F
=
k
e
q
1
q
2
r
2
,
{\displaystyle F=k_{e}{\frac {q_{1}q_{2}}{r^{2}}},}
where ke is Coulomb's constant (ke ≈ 9×109 N⋅m2⋅C−2),[7] 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).
Being an inverse-square law, the law is analogous to Isaac Newton's inverse-square law of universal gravitation, but gravitational forces are always attractive, while electrostatic forces can be attractive or repulsive.[8] Coulomb's law can be used to derive Gauss's law, and vice versa. The two laws are equivalent, expressing the same physical law in different ways.[9] The law has been tested extensively, and observations have upheld the law on a scale from 10−16 m to 108 m.[10]
