A mass spectrometer,sketched below, is a device used to separate different ions. Suchions with a well-defined velocity vo enter through aslit into a region of uniform magnetic field B, where they follow asemicircular path until they strike the detector slit above theentry slit. The distance between the entry and the detector slitsis d = 1.40 m.
Chlorine ions of mass 35 amu (1 amu equals1.66×10-27 kg), carrying a charge of+1e enter the spectrometer with initial speed ofvo = 6.80×105 m/s.
What value of B is required for these ions to hit the detector?
Equally charged chlorine ions of mass 37 amunow enter the spectrometer.
How close to the detector slit will they impact?
