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.
If the electron is shot in horizontally at v= m/s, just
above the bottom plate, how strong should the electric field be so that the
electron just misses the top plate upon exiting the plates? The
two plates are separated by a distance d= m?
