Electrons in a cathode ray tube start from rest and are accelerated through a potential difference of 12.0 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 320 V between the plates. The plates have length 8.50 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. What is the change in the y -position of the beam as it leaves the capacitor?
