# \(\alpha\) Day Problem 1

If 2 elementary charged particles interact with each other electromagnetically. Also, it is given that interaction has some strength, then find the number/factor characterizing this strength.

*Details and Assumptions*

Planck's constant(h) = 6.626 X \({10} ^{-24}\) Js [You may use reduced constant as well]

Speed of light(c) = 3 X \({10}^{8}\) m\({s}^{-1}\)

Permittivity factor = 9 X \({10}^{9}\) \(N{m}^{2}{C}^{-2}\)

Round your answer to 2 decimal places and in the form (decimal E n)
