Dimension of the electric charge

AI Thread Summary
The discussion focuses on determining the dimensions of electric charge in terms of mass, length, and time. It concludes that the dimensions can be expressed as kg^(1/2)*m^(3/2)/s. The relationship is derived from Coulomb's law, assuming permittivity is dimensionless, which leads to the conclusion that q^2/r^2 has dimensions of force. Additionally, references to Max Born's work and Einstein's theory of relativity are mentioned in relation to the cgs system. The thread also notes the age of the discussion, indicating that reviving old threads is generally discouraged.

could someone told me an experiment that ı can find the dimensions of the electric charge in therms of m, kg, sec
the answer is kg^(1/2)*m^(3/2)/sn it can be found by assuming the epsilon zero is dimensionless
please say me an experiment that i can check it :confused: :confused:

If permittivity is dimensionless, then from Coulomb's law, q^2/r^2 has dimensions of force. That's all you need to prove it.
 
Check out Max born's Einsteins's theory of relativity. He uses the cgs. system. e=cm(gm cm)^.5/sec. But what is the square root of a gram centimeter?
 
Hello Brian, welcome to Physics Forums.
Are you aware this thread is over 7 years old?

Resurrecting old threads without good reason is frowned on.

It may be shown from the equations of electromagnetism, by James Clerk Maxwell in the 1860’s, that the speed of light in the vacuum of free space is related to electric permittivity (ϵ) and magnetic permeability (μ) by the equation: c=1/√( μ ϵ ) . This value is a constant for the vacuum of free space and is independent of the motion of the observer. It was this fact, in part, that led Albert Einstein to Special Relativity.
