Question

what do you mean by charges to mass ratio?​

Answer 1

Here is your answer,

In 1897, J.J Thomson major it by using cathode ray tube and applying electrical and magnetic field perpendicular to each other as well as to the path of electron.

Thomson was able to determine the value of

$1.75 8820 × 10 power^{11} kg^{-1}$

i hope it will helps you.

Answer 2

Answer:

The Determination of the Charge to Mass Ratio of the Electron. A magnetic field produced by Helmholz coils is used to deflect electrons into circular paths whose radii are known. By knowing the energy of the electrons and the magnetic field strength, the ratio of the charge to mass (e/m) of the electron is determined.
