Coulomb Constant

The value of the Coulomb Constant (K), an important value in physics, given in SI cgs units of (N*m²)/C² is:

 , where:

k = Coulomb Constant ((N*m²)/C²⁾

 = Electric Constant (Fa/m)

 . where:

r_n = Radius at different orbits n (m)

h = Planck's Constant (J*s)

n = Number of Orbit

Z = Atomic Number

e = Elementary Charge (C)

k_e = Coulomb Constant ((N*m²)/C²)

m_e = Electron Mass (kg)

 , where:

 = Fine Structure Constant

k_e = Coulomb Constant ((N*m²)/C²)

e = Elementary Charge (C)

 = Dirac's Constant (J*s)

c = Speed of Light (m/s)

 , where:

F = Force between two charged points (N)

k = Coulomb Constant ((N*m²)/C²)

q₁ = Charge of point 1 (C)

q₂ = Charge of point 2 (C)

r = Distance between points (m)
