Question

When a charged particle enters a region of uniform magnetic field it follows a circular path, as indicated in the figure. (a) Is this particle positively or negatively charged? positive negative Explain. This answer has not been graded yet. . (b) Suppose that the magnetic field has a magnitude of 0.130 T, the particle's speed is 6.0 106 m/s, and the radius of its path is 96.3 cm. Find the mass of the particle, given that its charge has a magnitude of 1.60 1019 C. Give your result in atomic mass units, u, where 1 u = 1.67 1027 kg. u

Explanation / Answer

a)

here

according to the right hand rule , a positively charged particle would experience a force to the left . since the particle is experiencing a force to the right , it must be negatively charged

b)

m = e * r * B / v

m = (1.6 * 10^-19 * 0.963 * 0.13) / (1.67 * 10^-27 * 6 * 10^6)

m = 2 u
