Answer:
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:
{\displaystyle F=k_{e}{\frac {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. In the case of a single stationary point charge, the two laws are equivalent, expressing the same physical law in
Explanation:
Explanation:
According to Coulomb’s law, the force of attraction or repulsion between two charged bodies is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. It acts along the line joining the two charges considered to be point charges.
(Or)
Coulomb's law states that the electrical force between two charged objects is directly proportional to the product of the quantity of charge on the objects and inversely proportional to the square of the separation distance between the two objects.
Coulomb's law can be stated as :
F = (1/4π∈) * (q₁q₂)/d²
