Coulombs Law

What is Coulomb's Law?

Back

Coulomb's Law describes the force between two charged objects. It states that the electric force (F) between two charges (q1 and q2) is directly proportional to the product of the magnitudes of the charges and inversely proportional to the square of the distance (r) between them: F = k * (|q1 * q2| / r^2), where k is Coulomb's constant.

What happens to the electric force if the distance between two charges is doubled?

Back

If the distance between two charges is doubled, the electric force between them becomes one-fourth of its original value, as force is inversely proportional to the square of the distance.
