Problem

Two large vertical and parallel metal plates having a separation of

1 \text{ cm}

are connected to a DC voltage source of potential difference

X

. A proton is released at rest midway between the two plates. It is found to move at

45^\circ

to the vertical JUST after release. Then

X

is nearly [2012] a.
