Homework Help: What is potential difference uniform electric field

  1. Jan 29, 2009 #1
    1. The problem statement, all variables and given/known data

    What is the potential difference (in V) between xi = 18.5 cm and xf = 82.2 cm in the uniform electric field Ex = 4920 V/m?

    2. Relevant equations

    Not sure?

    3. The attempt at a solution

    Its simple but I am having problems figuring it out. I have a feeling it has to do with q1 and q2.
