Homework Help: Potential From an Electric Field

  1. Jan 28, 2008 #1
    I have been trying to calculate the potential difference between to points. In doing so, I have tried taking [tex]\int[/tex] -E * dl, in which I end up with -E*4, but that does not include the point charge, and I'm just not sure what I need to do to Calculate the potential with the addition of the point charge.

    A uniform electric field of 8 kN/C is in the x direction. A positive point charge Q = 3 micro Coloumbs is released from rest at the origin.
    --What is the potential difference V(4 m) - V(0)?

    You're doing OK. The potential difference only depends on the field, not on the charge you are putting in the field. (I suspect there will be addition questions for this problem where you will need to use the charge.)
