Two isotopes of carbon, carbon-12 and carbon-13, have masses of 1.993 10-26 kg and 2.159 10-26 kg, respectively. These two isotopes are singly ionized ( e) and each is given a speed of 6.50 105 m/s. The ions then enter the bending region of a mass spectrometer where the magnetic field is 0.5700 T. Determine the spatial separation between the two isotopes after they have traveled through a half-circle.
