Two large vertical and parallel metal plates having a separation of 1cm1cm1cm are connected to a DCDCDC voltage source of potential difference XXX. A proton is released at rest midway between the two plates. It is found to move at 45∘{45^ \circ }45∘ to the vertical JUST after release. Then XXX is nearly
