Two isotopes of carbon, carbon-12 and carbon-13, have masses of 19.93 10-27 kg and 21.59 10-27 kg, respectively. These two isotopes are singly ionized (+e) and each is given a speed of 6.75 105 m/s. The ions then enter the bending region of a mass spectrometer where the magnetic field is 0.8400 T. Determine the spatial separation between the two isotopes after they have traveled through a half-circle. _____________m
