Question
How charge/mass ratio is measured?
Open in App
Solution
The determination of the charge to the mass ratio of the electron is given method A magnetic field produced by Helmholtz coils is used to deflect electrons into the circular paths whose radii are known, By knowing the energy of the electrons and the magnetic field strength, the ratio of the charge to the mass (e/m) is determined. And experimentally determined charge by mass is equal to 1.758820024×1011C/Kg
