4PRACTICE PROBLEM
A mass spectrometer's ion source generates electrically charged particles with masses of 3.2 × 10-25 kg and charges of +2 e. The charged particles are accelerated through an electrical field and acquire an energy of 0.40 MeV. Then, the particles pass through a uniform magnetic field of magnitude 1.00 T. Find i) the speed and ii) the radius of the circular path of the charged particles.
