What Is The Charge To Mass Ratio Of Electron?
What Is The Charge To Mass Ratio Of Electron? = 1.602 10-19 coulombs. Why is the charge to mass ratio of an electron constant? The ratio of electromagnetic for a cathode ray is fixed at 1.758820×1011C/kg. It is equal to the ratio of e/m for an electron. This is because cathode rays consist of electrons.
