Question

According to coulomb's law, force between two point charges is

Answer 1

Coulomb's law states that: The magnitude of the electrostatic force of attraction or repulsion between two point charges is directly proportional to the product of the magnitudes of charges and inversely proportional to the square of the distance between them.

Answer 2

Answer: Coulomb's law states that the force between two charged bodies is inversely proportional to the square of the distance between them and directly proportional to the product of their charges.

Explanation: In 1785, French scientist Charles Augustin de Coulomb developed a concrete mathematical relationship between two electrically charged things. He published an equation for the force, often known as Coulomb's law or Coulomb's inverse-square law, that pulls two bodies toward or away from one another.

According to this law, the force of attraction or repulsion between two point charges is directly proporitonal to the product of their charges and inversely proportional to the square of the distance separating them. It applies along the line joining the two point charges .Mathematically, it can be written as :

F =k$\frac{q_{1}q_{2} }{r^{2} }$

where, q₁ and q₂ are the point charges

           k is Coulomb's consatnt

           r is the distance between the point charges

Coulomb's Rule says that Kr² = r²₀ if the force between two charges separated by a distance of "r₀" in a vacuum is equivalent to the force between the same charges separated by a distance of "r" in a medium.

Hence, according to Coulomb's law, force between two point charges is

directly proportional to the product the charges and inversely proportional to the square of the distance.
