Chapter 22, Problem 28P
You are working on a research project in which you must control the direction of travel of electrons using deflection plates. You have devised the apparatus shown in Figure P22.28. The plates are of length ℓ = 0.500 m and are separated by a distance d = 3.00 cm. Electrons are fired at vi = 5.00 × 106 m/s into a uniform electric field from the left edge of the lower, positive plate, aimed directly at the right edge of the upper, negative plate. Therefore, if there is no electric field between the plates, the electrons will follow the broken line in the figure. With an electric field existing between the plates, the electrons will follow a curved path, bending downward. You need to determine (a) the range of angles over which the electron can leave the apparatus and (b) the electric field required to give the maximum possible deviation angle.

A uniform electric field of magnitude 2000 N/C has been set up between two horizontal plates by charging the lower plate positively and the upper plate negatively. The plates have length L = 12.0 cm and separation d = 3.00 cm. An electron is then shot between the plates from the left edge of the lower plate. The initial velocity of the electron makes an angle of 45o with the lower plate and has a magnitude of 6.00 x 106 m/s. a. Will the electron strike one of the plates?b. If so, which plate and how far from the left edge will the electron strike?
An electron is to be accelerated in a uniform electricfield having a strength of 2.00 x 106 V/m .
(a) What energy in keV is given to the electron if it is accelerated through 0.400 m?
(b) Over what distance would it have to be accelerated to increase its energy by 50.0 GeV?
An electron with a speed of 5.63 × 108 cm/s in the positive direction of an x axis enters an electric field of magnitude 1.81 × 103 N/C, traveling along a field line in the direction that retards its motion. (a) How far will the electron travel in the field before stopping momentarily, and (b) how much time will have elapsed? (c) If the region containing the electric field is 4.23 mm long (too short for the electron to stop within it), what fraction of the electron’s initial kinetic energy will be lost in that region?
