Coulomb's Law, named after French physicist Charles-Augustin de Coulomb, is a fundamental principle in electromagnetism that describes the force between two point electric charges. The law states that the magnitude of the electrostatic force (F) between two point charges is directly proportional to the product of the magnitudes of the charges (q1 and q2) and inversely proportional to the square of the distance (r) between them. Mathematically, this is expressed as F = k * (q1 * q2) / r^2, where k is Coulomb's constant, approximately equal to 8.9875 × 10^9 N m^2/C^2.
Coulomb's Law is a vector quantity, meaning it has both magnitude and direction. The direction of the
The law was first formulated by Coulomb in 1785, based on his torsion balance experiments. It laid
In modern physics, Coulomb's Law is still widely used, although it is often supplemented by more advanced
