What is Mass-to-charge ratio?
The '''mass-to-charge ratio''' is a [[physical quantity]] (it is an amount that can be measured). The SI unit is [[kg]]/[[Coulomb|C]], which is [[kilogram]]s divided by the [[coulomb]]. Sometimes the '''charge-to-mass''' ratio is used instead. In a vacuum, all particles with the same mass-to-charge ratio move in the same path, when in the same strength of electric and magnetic fields. It is important for things like [[mass spectrometry]].
