WebA mass spectrometer ionizes atoms and molecules with a high-energy electron beam and then deflects the ions through a magnetic field based on their mass-to-charge ratios ( m/z m/z ). The mass spectrum of a sample shows the relative abundances of the ions on the y-axis and their m/z m/z ratios on the x-axis. If z = 1 z = 1 WebExplanation:When a charged particle of mass m and charge q moves with velocity v in a uniform magnetic field B, it experiences a magnetic force given by:F = qvB sin θwhere θ is the angle between the velocity of the charged particle and the magnetic field. This force acts perpendicular to both the velocity and the magnetic field, and causes the charged …
