An electron enters a region of constant electric field that is produced by a parallel-plate capaci- tor as shown in the figure below. The electron enters with a speed of 4.55 x 106 m/s and exits deflected downward a distance of 0.618 cm. What is
(a) the magnitude of the electric field pro- duced by the capacitor and
(b) the velocity of the electron when it exits the capacitor. The distance from the electron entry to exit is 2.25 cm.
