Hi
This may sound like a trivial question, but I'm a beginner physics student and need some help understanding what the k constant is from Coloumb law.
[tex] F_e = k_e\frac{k_1 k_1}{r^2} [/tex]
where
[tex]k_e = \frac{1}{4\piε_0} [/tex]
I did read a bit about it and I have two questions:
1. Why is k, the proportionality constant, necessary and what is its physical meaning? And where does the /pi come from?
2. How can you measure it?
Thank you
