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.
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).
