Question

Define Coulomb's law?

Answer 1

Coulomb's law states that there is an attractive or a repulsive force between any two charged bodies spearated by a distance
Or ,
The force between two electrically charged bodies is directly proportional to the charges of the bodies and inversely proportional to the square of the distances between them.

F = k * q1 * q2 / r^2

Where, q1 and q2 are the charges on the body and r is the distance between the centre of masses of the two bodies.

Here k is a constant which actually is 1/4π*absella(0) which has a value of approximately 9*10^9 Coulomb - metre.

Answer 2

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.
