Coulomb's Constant Question

  1. Feb 6, 2008 #1
    I'm sure I'm missing something simple here, but to the point:

    I calculate the electric field a distance r from a uniform straight infinite line charge using Gauss' Law and get an answer; I do the same calculation using Coulomb's law and get the same answer but a pi remains in the denominator (that was not there in the Gauss' Law solution). I don't know how to enter the equation here, but in both answers the numerator is the linear charge density. The Gauss' Law denonminator is 2r times epsilon; Coulomb's law denominator is 2(pi)r times epsilon. Help!

    oops!

    Sorry, all; I just realized I posted this in the wrong forum.
