A mass spectrometer has an adjustable magnetic field. When the magnetic field is 7.000e-2 T, a singly ionized hydrogen atom (a proton) will strike the detector at a particular location. Suppose a triply-ionized carbon 12 atom, whose mass is by definition 12 u (where1 u = 1.66×10−27 kg) enters thespectrometer at the same speed as the proton. What is the strength of the magnetic field that will cause it to strike the detector at the same location as the proton?
