A mass spectrometer is used to separate aluminum isotopes. The lightest aluminum isotope ( 13 protons and 10 neutrons )and the heaviest aluminum isotope ( 13 protons and 18 neutrons ) need to be separated by 15 centimeter on the detector of the mass spectrometer. The aluminum is ionized once ( 1 electron is missing ). Assume the mass of a neutron is the same as the mass of a proton. Pick the velocity and the magnetic field.
