Coulomb's law calculates the electrostatic force between two point charges.
According to Coulomb's law, the electrostatic force between two point charges is inversely proportional to the square of the distance between them.
Coulomb discovered that the force between bodies with like electrical charges (i.e., both positive or both negative) is repulsive, meaning they push each other away.
The equation for Coulomb's law is: F = k * (q1 * q2) / r^2, where F is the electrostatic force, k is Coulomb's constant, q1 and q2 are the magnitudes of the two point charges, and r is the distance between them.
Coulomb showed that the force between oppositely charged bodies (i.e., one positive and one negative) is attractive, meaning they pull each other towards each other.
