What is the name of the constant of proportionality in Coulomb's law that describes the electrostatic force between two point charges?
A. Planck constant
B. Boltzmann constant
C. Coulomb constant✓ Correct Answer
D. Stefan-Boltzmann constant
💡 Solution & Explanation
Coulomb constant appears in the mathematical expression for electrostatic force between stationary point charges in a vacuum. Its numerical value depends on the system of units used, typically expressed in newton meter squared per coulomb squared. Planck constant relates photon energy to its frequency in quantum mechanics.
