The plates are of length = 0.250 m and are separated by a distance d = 1.58 cm. Electrons are fired at v; = 5.10 × 106 m/s into a uniform electric field from the left edge of the lower, positive plate, aimed directly at the right edge of the upper, negative plate. Therefore, if
there is no electric field between the plates, the electrons will follow the broken line in the figure. With an electric field existing between the plates, the electrons will follow a curved path, bending downward.
(a) Determine the range of angles (in degrees) over which the electron can leave the apparatus. (Assume 0 is measured counterclockwise from the +x-axis. Enter your answers as a comma-separated list from smallest to largest. Do not enter units in your answer.)

In figure 2, an upwardly oriented uniform electric field E⃗ of a magnitude of 2.0 × 103 N / C has been established between two horizontal plates by charging the lower plate positively and the upper plate negatively. The plates have a length L = 10.0 cm, and they are at a distance of d = 2.0 cm. An electron is sent between the plates from the left end of the lower plate. The initial velocity ⃗v0 of the electron forms an angle θ = 45◦ with the lower plate, and its magnitude is 6.0 × 106 m / s (a) Will the electron touch one of the plates? (b) If so, determine which one. Then find how far horizontally from the left end the electron will strike.
