In your laboratory, you set up an experiment with a mass spectrometer used to separate ionized particles. A single ionized particle of mass 3.27 × 10^-25 kg and with an energy of 1.00 MeV moves in a circle of radius 18.00 cm in a uniform magnetic field. What would be the orbital radius of a doubly ionized particle of mass 1.59 × 10^-25 kg entering the same magnetic field with an energy of 1.00 MeV?
