A mass spectrometer is a mass spectrometer device like the one shown in the attached figure. A particle of total charge total q = 4.8-10-19 C is directed with velocity of magnitude v = 4.5 - 106 m/s in a space where there exists a uniform magnetic field of magnitude B = 0.8-10-4T describing a circular orbit of radius r = 1.2 m. Determine the mass m of the particle in kg. V B m m1 Detector
