Particle round about. Figure 28-29 shows 11 paths through a region of uniform magnetic field. One path is a straight line: the rest are half-circles. Table 28-4 gives the masses, charges, and speeds of 11 particles that take these paths through the field in the directions shown. Which path in the figure corresponds to which particle in the table? (The direction of the magnetic field can be determined by means of one of the paths, which is unique.)
