Homework Help: Potential difference, uniform electric field

  1. Nov 13, 2007 #1
    1. The problem statement, all variables and given/known data

    What is the potential difference between A and B?


    2. Relevant equations


    3. The attempt at a solution

    I got the distance between the points to be about 0.0761577 m

    After this I multiplied it by 1000, giving about 76.1577, which is incorrect

    Thanks in advance for the help!

    Equipotential surfaces are perpendicular to the electric field lines of froces. Potential differece = VB - VA = E*d where d is the perpenicular distance between two parallel planes passing through A and B
