In a computer monitor, electrons are accelerated from rest through a potential difference in an electron gun

In a computer monitor, electrons are accelerated from rest through a potential difference in an €œelectron gun€ arrangement (Fig. 16.26).

(a) Should the left side of the gun be at (1) a higher, (2) an equal, or (3) a lower potential than the right side? Why?
(b) If the potential difference in the gun is 5.0 kV, what is the €œmuzzle speed€ of the electrons emerging from the gun?
(c) If the gun is directed at a screen 25 cm away, how long do the electrons take to reach the screen?
