An electron gun creates a beam of electrons moving
Chapter 23, Problem 23.19(choose chapter or problem)
An electron gun creates a beam of electrons moving horizontally with a speed of 3.3 * 107 m/s. The electrons enter a 2.0-cm-long gap between two parallel electrodes where the electric field is E u = (5.0 * 104 N/C, down). In which direction, and by what angle, is the electron beam deflected by these electrodes?
