    [Ignore]How to derive magnitude of Electric field to this?

    1. The problem statement, all variables and given/known data
    My book states that
    [tex]|E| = \frac{2kQ}{d^2} = 2\pi k\sigma [/tex]
    I thought k, the coulomb constant is [tex]\frac{1}{4\pi\epsilon0}[/tex]


    2. Relevant equations



    3. The attempt at a solution
