Figure 19−41 shows an electron entering a parallel−plate capacitor with a speed of 5.45 × 106 m/s. The electric field of the capacitor has deflected the electron downward by a distance of 0.618 cm at the point where the electron exits the capacitor. Find (a) the magnitude of the electric field in the capacitor and (b) the speed of the electron when it exits the capacitor.
