Find the time of flight as electron passes between plates

Reference no: EM13669131

In the neck of the picture tube of a certain black-and-white TV set, an electron gun contains two charged metallic plates 2.60 centimeter apart. An electric force accelerates each electron in the beam from rest to 9.40 percent of the speed of light over this distance. (Neglect the effects of relativity in your calculations.)

(a) Find the kinetic energy of the electron as it leaves the electron gun. Electrons carry this energy to a phosphorescent material on the inner surface of the television screen, making it glow.

(b) For an electron passing between the plates in the electron gun, find the magnitude of the constant electric force acting on electron.

m/s2

(d) Find the time of flight as the electron passes between the plates.
