In a mass spectrometer, a doubly charged ion having a particular velocity is selected by using a magnetic field of 100 mT perpendicular to an electric field of 1.0 kV/m. This same magnetic field is then used to deflect the ion in a circular path with a radius of 15 mm. Find
(a) The mass of the ion and
(b) The kinetic energy of the ion.
(c) Does the kinetic energy of the ion increase in the circular path? Explain.
