You send a beam of oxygen ions through a mass spectrometer like the one shown in Fig.27.24. The nuclei emerge from the velocity selector at 2.00×104 m>s and encounter a magnetic field of magnitude B′ = 0.0500 T. All the ions have charge +1.60×10−19 C, but some are the isotope 16O (mass 2.66×10−26 kg) and some are the isotope 18O (mass 2.99×10−26 kg). Find the radius of the semicircular path followed by (a) the 16O ions and (b) the 18O ions.
