An electron enters the region between the plates of a parallel plate capacitor at a point equidistance from either plate. The capacitor plates are `2 xx 10^(-2)m` apart and `10^(-1)m` long. A potential difference of 300 V is kept across the plates. Assuming that the initial velocity of the electron is parallel to the capacitor plates, calculate the largest value of the velocity of the electrons so that they do not fly out of the capacitor at the other end.
