Homework Help: Electric potential along the centre line between 2 charged plates

  1. Jan 2, 2010 #1
    1. The problem statement, all variables and given/known data
    Explain why in the absence of any other charged bodies, the potential will be zero along the centre line between plates

    2. Relevant equations

    3. The attempt at a solution
    not sure how to explain it. is this because that the electric field in that region is zero?

    Electric potential is the algebraic sum of the potentials due to either of the two plates. It cancels out along the centre line. (since the plate charges are equal and opposite.)
