Final answer:
Coulomb's Law describes the electrostatic force between charged particles, being directly proportional to the product of the charges and inversely proportional to the distance squared between them.
Step-by-step explanation:
The best description of Coulomb's Law is that it defines the force between charged particles and the distance separating them. Coulomb's Law states that the electrostatic force between charged objects is proportional to the charge on each object and inversely proportional to the square of the distance between the objects. This means if you double the charge on one of the objects, the force will double as well; however, if you double the distance between the two objects, the force will decrease by a factor of four (since the distance is squared). Coulomb's Law is a fundamental part of understanding electrostatic phenomena in physics and chemistry and is crucial when studying the behavior of particles at the atomic level. French physicist Charles Coulomb first published this law, which has since been verified to high precision by modern experiments.
