Homework Help: Electric Field distributed Uniformly along the X-axis

  1. Sep 4, 2008 #1
    1. The problem statement, all variables and given/known data
    A charge Q is distributed uniformly along the x axis from x1 to x2. If x1=0m, x2= 4.82m, and the charge Q = 3.13 microcoulombs, what is the Magnitude of E of the electric field at x0= 11.7m on the x-axis. Assume that x0>x2>x1. Answer in unitsof N/C.

    2. Relevant equations

    dE= kdq/r^2

    3. The attempt at a solution
    Ok so I got the integral down as (KQ)/((x2-x1)(x0-x)^2) from x1 to x2. And I simplified the integration KQ/(x2-x1) times the integral of 1/(x0-x) from x1 to x2. I then plugged in the numbers and got 3.099x10^3 N/C which is incorrect. Did I miss any crucial steps?
