Electric potential

  1. Nov 19, 2004 #1
    if you had two point charges of charge +q each, where would the electric potential vanishes, other than at infinite?

    the thing i am reading says "nowhere", though i am wondering, why can there not be 0 electric potential exactly halfway between the charges?

    Nowhere. The potential is not the field, so midway between the charges the potential is not zero but its derivative and therefore the electric field, is zero. The potential is a measure of how much energy you need, to get from infinity to that point.
