# Question

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