A cathode ray tube (CRT) is used to accelerate electrons in some televisions, computer monitors, oscilloscopes, and x-ray tubes. Electrons from a heated filament pass through a hole in the cathode; they are then accelerated by an electric field between the cathode and the anode. Suppose an electron passes through the hole in the cathode at a velocity of 1.0 x 10 m/s toward the anode. The electric field is uniform between the anode and the cathode and has a magnitude of 1.0x10 N/C . (a) What is the acceleration of the electron? (b) If the anode and the cathode are separated by 2.0 cm, what is the final velocity of the electron?
