Find a point charge a distance form a charged rod

  1. Apr 2, 2013 #1
    1. The problem statement, all variables and given/known data

    See image

    2. Relevant equations

    KQ/r^2

    3. The attempt at a solution

    I have seen several different ways of working this problem, but they have all failed on me.

    I tried this using the equation above from my book

    E = (8.99x10^9)(1036 C)/(4x10^-6m)

    E= 2.328x10^18 N/C

    I also tried using

    E = K*Q/sqrt(r^2+(L/2)^2)
    E = 1.86x10^11 N/C


    This was not correct. Please help. Thanks in advance!
