A fine horizontal beam of electrons, moving with a velocity of `5xx10^(6)ms^(-1)` enters the plates mid-way and produces a bright spot of light on a vertical screen `100 mm` beyond the edges of the plates. A potential difference of `10 V` is applieed to the plates. Calculate the deflection of the spot from its initial position.
