    aaaaa :biggrin: that sorta went over my head.

    Can you do it with this relation -

    V = k(q/d)

    i.e potential difference at a distance d from a charged particle q of a unit charge brought from infinity.

    There's something wrong with latex...its showing my old codes.

    Yep got that --

    In V = k(q/d) substitute q with (Ed2)/k (derived from E.F at a point from a source charge q)

    Solve and you get it.
