Coulomb's Law:Coulomb's law is a fundamental principle in electrostatics that states the force between two stationary, electrically charged particles is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.
Electric Charge:Electric charge is a fundamental property of matter that can be positive or negative. It is the source of the electric force, which can attract or repel other charged particles.
Electric Force:Electric force is the force of interaction between two electrically charged particles. It can be attractive or repulsive, depending on the signs of the charges.
