Maximum electrostatic force problem

  1. Apr 26, 2005 #1
    im studyng electromechanics and this is a problem i found

    gived a fixed point A charged with Q1 charge,
    gived a electrical wire of fix lenght L and charge Q2 distributed uniformly in it,
    the wire is fixed at its edges at 2 points along a line L,
    the line L and the point A are separated by a fixed distance s
    to find the curve of the wire that provides the strongest attraction to the fixed point
    the wire is supposed withouth weight

    somebody could explain what are the math involved here? thanks
