The mass spectrometer described in Example 26.2 is a simple but largely obsolete design. Modern mass spectrometers generally use a single detector at a fixed location, and they scan the magnetic field strength B by varying the current in an electromagnet. The known value of B at the time a detection is made then allows the charge-to-mass ratio of the detected species to be determined. Furthermore, modern designs don't use the full semicircle as for the mass spectrometer in Example 26.2 but generally take the particles through a smaller circular arc. (Figure 1) shows the magnetic portion of such a mass spectrometer. Ions enter the magnetic field after being accelerated through a potential difference of 2.75 kV. They enter moving perpendicular to the field region, a distance of r = 13 cm from the apex shown, and, if they have the appropriate charge-to- mass ratio, they strike the detector, which is located the same distance from the apex as the entrance slit.

An electron enters the region between two plates traveling along the x-direction with a speed of v = 4.78 x 106 m/s. Both plates are parallel to the x-y plane and are separated by 4.5 cm. The potential of the top plate at z = 4.5 cm is +100 V while the potential of the bottom plate at z = 0 cm is 0 V. What is the direction of the magnetic field between the plates that is required so that the electron continues traveling in a straight line along the x-direction in this region?
1. You've recently read about a chemical laser that generates a 20-cm-diameter, 25 MW laser beam. One day, after physics class, you start to wonder if you could use the radiation pressure from this laser beam to launch small payloads into orbit. To see if this might be feasible, you do a quick calculation of the acceleration of a 20-cm-diameter, 100 kg, perfectly absorbing block. What speed would such a block have if pushed horizontally 100 m along a frictionless track by such a laser?
