Two parallel, charged plates, both of length L= m create
an electric field between them as shown here. An electron is shot into a region where an electric field exists, as shown
here.
The electron is shot in with a speed of v= m/s, at an angle of 
= degrees,
right at the left edge of the bottom plate. The electric field has a strength of
E= N/C. Assuming the electron doesn't hit the upper
plate, where will the electron strike the lower plate again?
