Electrons in a cathode ray tube start from rest and are accelerated through a potential difference of 13.8 kV. They are moving in the +x-direction when they enter the space between the plates of a parallel plate capacitor. There is a potential difference of 313 V between the plates. The plates have length 7.81 cm and are separated by 1.10 cm. The electron beam is deflected in the 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 while between the plates?

3.What is the kinetic energy of the electrons as they leave the plates?

The electrons in a cathode ray tube are emitted by a hot filament cathode and are accelerated by an electric field applied between the cathode and two orthogonal pairs of parallel plate electrodes. The beam passes through the gap between the electrodes and can be deflected up and down, or left and right if the parallel plates are appropriately biased. As the electrons pass through the electrodes, their kinetic energy increases. Assume the electrons are emitted from the cathode with...
