Coulomb's constant is a proportionality factor that appears in Coulomb's law as well as in other electric-related formulas. Denoted k e, it is also called the electric force constant or electrostatic constant, hence the subscript e. The exact value of Coulomb's constant is:
The Coulomb constant, the electric force constant, or the electrostatic constant (denoted k e, k or K) is a proportionality constant in electrodynamics equations. In SI units, it is equal to approximately 8 987 551 787.368 1764 N·m 2 ·C −2 or 8.99 × 10 9 N·m 2 ·C −2.

Electrostatic Force and Electric Charge Electrostatic Force (charges at rest ): • Electrostatic force can be attractive • Electrostatic force can be repulsive • Electrostatic force acts through empty space • Electrostatic force much stronger than gravity • Electrostatic forces are inverse square law forces ( proportional to 1/r 2)
Coulomb's law is formulated as follows: F = Ke * q₁ * q₂ /r². where: F is the electrostatic force between charges , q₁ is the magnitude of the first charge (in Coulombs), q₂ is the magnitude of the second charge (in Coulombs), r is the shortest distance between the charges (in m), Ke is the Coulomb's constant.
Coulomb force, also called electrostatic force or Coulomb interaction, attraction or repulsion of particles or objects because of their electric charge.One of the basic physical forces, the electric force is named for a French physicist, Charles-Augustin de Coulomb, who in 1785 published the results of an experimental investigation into the correct quantitative description of this force.
d is the distance between the charged particles or objects. q 1 represents the quantity of charge of one particle. q 2 represents the quantity of charge of the other particle. k is called the proportionality constant or electrostatic constant. k = 9,000,000,000 N.m 2 /C 2. Notice that in Coulomb's law, we take the absolute value of the quantity of charge.
Coulomb's Law Equation. The quantitative expression for the effect of these three variables on electric force is known as Coulomb's law. Coulomb's law states that the electrical force between two charged objects is directly proportional to the product of the quantity of charge on the objects and inversely proportional to the square of the separation distance between the two objects.
Electrostatic force originates from the charges that are applied to or induced in probe and sample. It can be attractive or repulsive and its strength can be easily higher than that of the van der Waals forces. In principle we could derive all the electrostatic forces effects from Coulomb law if we were able to treat all volume and surface charges in our system.
