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 6.25 105 m/s. The ions then enter the bending region of a mass spectrometer where the magnetic field is 0.6200 T. Determine the spatial separation between the two isotopes after they have traveled through a half-circle.

A piece of copper wire has a resistance per unit length of 6.20 10-3 ?/m. The wire is wound into a thin, flat coil of many turns that has a radius of 0.150 m. The ends of the wire are connected to a 12.0-V battery. Find the magnetic field strength at the center of the coil.
