Which law of physics states that the force 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?
Faraday's Law
Coulomb's Law
Ampere's Law
Ohm's Law
Coulomb's Law
Coulomb's Law defines the electrostatic force of attraction or repulsion between two point charges. It states that this force is directly proportional to the product of the magnitudes of the charges and inversely proportional to the square of the distance between them.

Much like gravity pulls objects together based on their mass and distance, electric charges pull or push each other based on their charge magnitude and distance.
F=4╧А╬╡0тАЛ1тАЛr2q1тАЛq2тАЛтАЛ тАФ Magnitude of electrostatic force between two point charges
The electrostatic force acts along the straight line joining the two point charges. The magnitude of the force is determined by the product of the charge values, the inverse square of the distance, and the permittivity of the intervening medium.
Applies strictly to stationary point charges.
Follows an inverse-square law relationship with distance.
Acts along the line connecting the two charges.
Calculating atomic and molecular electrostatic interactions
Designing particle accelerators and electronic components
The permittivity of free space ╬╡0тАЛ is approximately 8.854├Ч10тИТ12┬аC2/(NтЛЕm2).
Option A relates to electromagnetic induction, Option C to magnetic fields from currents, and Option D to electrical resistance.
B is correct тАФ Coulomb's Law defines the electrostatic force between two point charges proportional to the product of charges and inversely proportional to the square of the distance.
Compare Coulomb's Law with Newton's Law of Gravitation as both share the inverse-square distance dependence.
