A proton accelerated through a potential of 12.0 kV enters a
device which has both an electric and a magnetic field, that are
perpendicular to each other as shown in the figure. This device is
known as a "velocity filter", because only protons with a given
velocity are not deflected and continue their trajectory along the
y-axis through the aperture...
