The Coulomb constant, the electric force constant or the electrostatic constant which is denoted by k or K is a proportionality constant in electrostatics equations. The value of K in SI units is equal to 8.98755 × 109 kg. m3. s–2.
Besides, what is called electrostatics?
electrostatics, the study of electromagnetic phenomena that occur when there are no moving charges—i.e., after a static equilibrium has been established. Charges reach their equilibrium positions rapidly, because the electric force is extremely strong.
Similarly one may ask, what is formula of electrostatic force?
Electric force formula can be obtained from Coulomb’s law as follows: → F = K q 0 q 1 r 2 r ^ Where, → F. is the electric force directed between two charged bodies.
What is J in electrostatics?
The Journal of Electrostatics is the leading forum for publishing research findings that advance knowledge in the fundamental science and engineering of electrostatics.

What is the value of k in Coulomb’s law?
This equation is known as Coulomb’s law, and it describes the electrostatic force between charged objects. The constant of proportionality k is called Coulomb’s constant. In SI units, the constant k has the value. k = 8.99 × 10 9 N ⋅ m 2 /C 2.
