Question: an electron with kinetic energy k is traveling along the...

Question details

An electron with kinetic energy K is traveling along the +x axis, which is along the axis of a cathode-ray tube as shown in the figure below. There is an electric field E = 9.00×10^4 N/C pointed in the +y direction between the deflection plates, which are d = 0.0500 m long and are separated by 0.0200 m.

.0200 m

1) Determine the minimum initial kinetic energy the electron can have and still avoid colliding with one of the plates. (Express your answer to three significant figures).
