In the MKS system of units, the proportionality constant in Coulomb's law is 1/( 4 pi �µ0 )
' �µ0 ' is the electrostatic permittivity of free space.
It does seem unnecessarily complicated. But there are reasons for it, and it all works out.
Answer2:
The constant used in Coulomb's law is one of the most important constants in Physics. It is related to Planck,s Constant, h. The permittivity e0= 1/zc where c is the speed of light and z is the free space impedance, z= w/q ; w is the quantum magnetic charge in webers ,volt-second and q is the quantum electric charge q. Planck's Constant h= qw = 2/3 E-33 and z = 375 ohms.= w/q
The q= 4/3 E-18 Coulomb and w = 500 E-18 volt second.
The quantum electric charge q=4/3 E-18 C x 6.25E18e/C= 25/3 e = (13U1d) in Quarks., U=Up and d=down.
The electron is an rms charge F= -e^2/4pi e0 r^2 = - e^2zc/22pir^2=e^2hc/2q^22pir^2= -alpha ch/2pir^2.
The Fine Structure Constant alpha = 0 .5 (e/q)^2 = .5( .16/4/3) = .5 (.12)^2 = .5 (.0144) = 7.2E-3
F = -ach/2pi r^2 = -vp/r where v=ac = 7.2E-3 300Mm/s = 2.16Mm/s.

In boyle's law which is held constant?
In case of BOYLE'S law,temperature is held constant! thank you!!
According to Charles's law for a fixed quantity of gas at constant pressure which of the given quantities is constant?
In Charles' Law, the mass is held constant which means that the pressure on the gas is constant.
What are the limitations coulombs law?
Limitations of coulombs law
What are the units of the Coulomb constant k which appears in Coulomb's law?
newtons * meters squared / coulombs squared
Is coulombs law a universal law?
No
What mathematical expression identifies the number of coulombs necessary to produce one mole of iron metal from an aqueous solution of iron III sulfate?
The law is:Needed electricity in coulombs = Faraday constant (96500 C) x number of molesSo 96500 coulombs are needed.
What is Avogardo's constant used for?
Well it is used in certain Chemical equations and to derive other constants. As an example the charge on an electron = 1.6019 x 10-19 coulombs. So a mole of electrons will be 6.023 x 1023 (Avagadro) x 1.6019 x 10-19 coulombs per mole = 96495 coulombs per mole which is Faraday's constant
How is coulombs law different from newton law?
Newtons law has to due with mass and ATTRACTION only Coulombs law has to due with charge and ATTRACTION AND REPULSION
What is coulombs constant?
It is 8.9875517873681764×109 N·m^2/C^2
How do you calculate electrostatic force?
coulombs law
Faraday law of elecrolysis?
W = (I*t*A)/(n*F)where:W = weight of plated metal in grams.I = current in coulombs per second.t = time in seconds.A = atomic weight of the metal in grams per mole.n = valence of the dissolved metal in solution in equivalents per mole.F = Faraday's constant in coulombs per equivalent. F = 96,485.309 coulombs/equivalent.
How do you calculate coulombs law?
Coulombs law is given by the equation:F=kq1*q2/r^2 This means that the force of attration between two particles is = to k(9.11810^9) times the product of their charges divided by the distance apart sqaured. The final units are in Newtons. And in this equation k is a constant given by: 9E9 N*m^2/C^2
What does the Q in coulombs law stand for?
Q refers to charges. Charges are measured in coulombs.
What is the drawback of coulombs law?
Coulumbs law is applicable only for static fields that is when charges are stationary
