    Study Notes

    Coulomb's Law

    • Coulomb's law states that the electrostatic force between two point charges is proportional to the product of the magnitudes of the charges and inversely proportional to the square of the distance between them.
    • Coulomb discovered that the repulsive force between bodies with like electrical charges is proportional to the product of the magnitudes of the charges and inversely proportional to the square of the distance between them.
    • In Coulomb's law, 'ke' represents the Coulomb constant, which is a constant of proportionality.
    • The formula for the electrostatic force between two point charges according to Coulomb's law is F = (ke * q1 * q2) / r^2, where F is the electrostatic force, q1 and q2 are the magnitudes of the two point charges, and r is the distance between them.
    • Coulomb's law is significant in the development of the theory of electromagnetism because it provides a fundamental understanding of the electrostatic force between charged objects and has been widely used to describe the behavior of electrically charged particles.
    • Charles-Augustin de Coulomb first published Coulomb's law in 1785.
