Question:

When a charged particle enters a region of uniform magnetic field, it follows a circular path, as indicated in FIGURE 22-44.

(a) Is this particle positively or negatively charged? Explain.

(b) Suppose that the magnetic field has a magnitude of 0.180 T, the particle's speed is 6.0 × 106 m/s, and the radius of its path is 52.0 cm. Find the mass of the particle, given that its charge has a magnitude of 1.60 × 10-19C. Give your result in atomic mass units, u, where 1 u = 1.67 × 10-27 kg.
