A beam of protons with various speeds is directed in the positive x direction. The beam enters a region with a uniform magnetic field of magnitude 0.49 T pointing into the page, as shown below. 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 1.23 105 m/s; that is, only these protons should be undeflected by the two fields.
(a) Determine the electric field that yields the desired
result.
= N/C + N/C + N/C
(b) Suppose the electric field is to be produced by a
parallel-plate capacitor with a plate separation of 2.5 cm.
What is the magnitude of the potential difference required between
the plates?
V
(c) Which plate in the figure should be positively charged?
(Make sure you understand why.)
bottom or top?

A uniform electric field of magnitude 148 kV/m is directed upward in a region of space. A uniform magnetic field of magnitude 0.42 T perpendicular to the electric field also exists in this region. A beam of positively charged particles travels into the region. Determine the speed of the particles at which they will not be deflected by the crossed electric and magnetic fields. (Assume the beam of particles travels perpendicularly to both fields.) m/s
