In the mass spectrometer of the diagram, neon ions (q = +e) come from the ion source and are accelerated through a potential difference V. The ions then pass through an aperture in a metal plate into a uniform magnetic field where they travel in semicircular paths until exiting into the detector. Neon ions having a mass of 20.0 u leave the field at a distance of 50.0 cm from the aperture. At what distance from the aperture do neon ions having a mass of 22.0 u leave the field? (1 u = 1.66 × 10ˆ’27 kg.)
