Electrons in a cathode ray tube start from rest and areaccelerated through a potential difference of 13.8 kV. They aremoving in the +x-direction when they enter the space between theplates of a parallel plate capacitor. There is a potentialdifference of 313 V between the plates. The plates have length 7.81cm and are separated by 1.10 cm. The electron beam is deflected inthe negative y-direction by the electric field between the plates.where P = 7.81 and Q = 313.
1.What is the value of Δy, the vertical deflection?
2.Through what potential difference do the electrons move whilebetween the plates?
3.What is the kinetic energy of the electrons as they leave theplates?
