# $$\alpha$$ Day Problem 1

Level pending

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)
