Question

A mass spectrometer is used to separate isotopes. If the beam emerges with a speed of 253 km/s and the magnetic field in the mass selector is 4.0 T, what is the distance in mm between where the following ions are detected? Remember that the ions trace a semicircular path before being detected. Note: the superscript number in the following says how many nucleons (protons and neutrons) are contained in the ion. The mass of a nucleon is 1.66 10-27 kg, and you should ignore the mass of the electrons.

  ¹²C⁺ and ¹⁴C⁺
