Coulomb's constant, denoted as k, is a proportionality constant that relates the electrostatic force between two charged objects to their charges and the distance between them.
Electric Field: The electric field is a region around a charged object where other charged objects experience an electric force.
Electric Potential Energy: Electric potential energy is the energy stored in a system due to the arrangement of charges.
Electrostatic Force: Electrostatic force refers to the attractive or repulsive force between two charged objects due to their electric charges.
