The Coulomb Constant, denoted as k , is a fundamental physical constant used in electrostatics. It quantifies the strength of the electrostatic force between two charged objects. The value of the Coulomb Constant is approximately 8.99 \times 10^9 \, \textN m^2/\textC^2 , where \textN stands for newtons, \textm for meters, and \textC for coulombs, the unit of electric charge. This constant is part of Coulomb's Law, which states that the force between two point charges is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. The Coulomb Constant helps in calculating the magnitude of this force, making it essential for understanding electric interactions in physics.
