The mass-to-charge ratio (m/Q) is a physical quantity relating the mass (quantity of matter) and the electric charge of a given particle, expressed in units of kilograms per coulomb (kg/C). It is most widely used in the electrodynamics of charged particles, e.g. in electron optics and ion optics. It appears … Ver más When charged particles move in electric and magnetic fields the following two laws apply: • Lorentz force law: F = Q ( E + v × B ) , {\displaystyle \mathbf {F} =Q(\mathbf {E} +\mathbf {v} \times … Ver más In the 19th century, the mass-to-charge ratios of some ions were measured by electrochemical methods.
