Q. An electron gun consists of two parallel, oppositely charged, flat plates (see diagram in Moodle). A nearly uniform electric field exists between these plates. The positively charged plate has a hole in the center, through which, high speed electrons exit. The electrons are initially at rest in the electric field near the negatively charged plate. The field causes the electrons to accelerate and pass through the hole in the positively charged plate. Calculate each of the following if the electrons exit the field with a speed of 4.45x106 m/s and the distance between the plates is 2.07 cm.

Find the potential energy lost by the electron as it passes through the electron gun.

Find the potential difference between the charged plates.

Find the strength of the electric field between the plates of the electron gun.
