Suppose that an ion source in a mass spectrometer produces doubly ionized gold ions (Au^2+), each with a mass of 3.27 x 10^-25 kg. The ions are accelerated from rest through a potential difference of 2.00 kV. Then, a 0.470-T magnetic field causes the ions to follow a circular path. Determine the radius of the path.
