Suppose that an ion source in a mass spectrometer produces doublyionized gold ions (Au2+), each with a mass of 3.27 10-25 kg. Theions are accelerated from rest through a potential difference of1.40 kV. Then, a 0.560 T magnetic field causes the ions to follow acircular path. Determine the radius of the path.

The answer is in the form of m
