Confirm that e^2 x coulomb's constant=1

  1. Sep 6, 2009 #1
    1. The problem statement, all variables and given/known data
    I'm not really sure how to go about this


    2. Relevant equations

    whenever I plug in the correct values I don't get 1. Unless I'm supposed to use au.



    3. The attempt at a solution

    Well what is Coulomb's constant?

    Am I correct in assuming that e is the elementary charge?

    it's 1/(4*pi*episolon naught) where episolon naught is 8.85 x 10^-12 F/m. yes, e is the elementary charge.

    Then there is nothing left to do since as you have now pointed out in your edited opening post, it is clear that

    [tex]e^2 \cdot\kappa \neq 1[/tex]
