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 8.016 × 105 m/s. the ions then enter the bending region of a mass spectrometer where the magnetic field is 0.6265 t. determine the spatial separation between the two isotopes after they have traveled through a half-circle. use 1.602 × 10-19 c as the elementary charge and give your answer to four significant figures.
