An electron with kinetic energy of 5 x 10-16 j is moving to, Ask an Expert

Academics

An electron with kinetic energy of 5 x 10-16 J is moving to the right along the axis of a cathode-ray tube as shown below. There is an electric field vector = (4 x 104 N/C) jhatbold in the region between the deflection plates. Everywhere else, vector = 0.

1) How far is the electron from the axis of the tube when it reaches the end of the plates? mm

2) At what angle is the electron moving with respect to the axis? (Positive angle measured counterclockwise with respect to the axis) °

3) At what distance from the axis will the electron strike the fluorescent screen?
