A mass spectrometer is used to separate isotopes 235U and 238U. A beam of mixed 235U and 238U ions travelling at 6500 m/s enters in a uniform magnetic field. Then the isotopes separate from each other by travelling along different semicircles within the magnetic field. Both the isotope ions carry +3|qe| charge, where qe = – 1.6E-19 C, and the isotope masses are 3.901E-25 kg for 235U and 3.951E-25 kg for 238U. If the semicircle radius of the 235U ions is 14.3 m, what is the separation of the isotopes (the difference between semicircle radii of the two isotopes in meter)?
