3. A CRT is used with an accelerating voltage of 750 V to accelerate electrons before they pass through deflecting plates, to which a deflecting voltage of 50.0 V is applied. (a) What speed do the electrons reach? (b) When the electrons travel through the deflecting plates, which are separated by a distance of 2.0 cm, what is the electric field strength between the plates? (c) What is the force that will deflect electrons as they pass through the plates? (d) At what rate will the electrons accelerate as they pass through the plates? (e) The plates have a length of 5.0 cm. For what length of time will the electrons be between the plates? (f) What is the deflection in a y-direction of the electrons as they pass through the plates? (g) If the screen is 0.20 m beyond the end of the deflecting plates, what deflection () will you see on the screen
