positive a direction. The beam enters a region with a
uniform magnetic field of magnitude 0.44 T pointing in the
negative z direction, as indicated in the figure(Figure 1). It
is desired to use a uniform electric field (in addition to the
magnetic field) to select from this beam only those protons
with a speed of 1.42 x 10 m/s - that is, only these
protons should be undeflected by the two fields.
Determine the magnitude of the electric field that yields the desired result.
