A mass spectrometer, sketched below, is a device used to separate different ions. Such ions with a well-defined velocity vo enter through a slit into a region of uniform magnetic field B, where they follow a semicircular path until they strike a detector slit a distance d above the entry slit. The distance between the entry and the detector slits is d = 1.90m. Chlorine ions of mass 35 amu (1 amu equals 1.66x10-27 kg), carrying a charge of +1e, enter the spectrometer with initial speed of vo = 5.50E5 meters/sec. What value of B is required for these ions to hit the detector?
