The image below shows a mass spectrometer, an analytical instrument used to identify the various molecules in a sample by measuring their charge-to-mass ratio e/m. The sample is ionized, the positive ions are accelerated (starting from rest) through a potential difference ΔV, and they then enter a region of uniform magnetic field. The field bends the ions into circular trajectories, but after just half a circle they either strike the wall or pass through a small opening to a detector. As the accelerating voltage is slowly increased, different ions reach the detector and are measured. Typical design values are a magnetic field strength B = 0.627 T and a spacing between the entrance and exit holes d = 5.83 cm. a)What accelerating potential difference ΔV is required to detect N2+? b)What accelerating potential difference ΔV is required to detect O2+? c)What accelerating potential difference ΔV is required to detect CO+?
