Coulomb's Law: Coulomb's law is the fundamental principle that describes the electrostatic force between two point charges. It states that the force between two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.
Electric Field: An electric field is the region surrounding a charged particle or object in which other charged particles experience a force. The electric field describes the strength and direction of the electrostatic force at every point in space.
Charge: Charge is a fundamental property of matter that can be positive or negative. The electrostatic force arises from the interactions between charged particles, with like charges repelling and opposite charges attracting.
