Problem 3:
In an ordinary television set, the electron beam consists of
electrons shot horizontally at the television screen with a speed
of about 5 x 107 m/s. How far does a typical electron fall as it
moves the approximately 40 cm from the electron gun to the screen?
For comparison, how far would a droplet of water shot horizontally
at 2 m/s from a hose drop as it moves a horizontal distance of 40
cm?
