Question

Is coulombs law in electrostatics applicable in all situations​

Answer 1

Coulomb law is not applicable in all situation because of the following reason :

1. the charges must be at rest
2. electric charge must be point charges
3. separation between the charges must be greater than the nuclear size(10^-15) because for distance less than 10^-15 strong nuclear force dominates over the electrostatic force.

Answer 2

Answer:

Coulomb law is not applicable in all situation because of the following reason : the charges must be at rest. ... separation between the charges must be greater than the nuclear size(10^-15) because for distance less than 10^-15 strong nuclear force dominates over the electrostatic force.
