Explanation:

1.In physics, the proton-to-electron mass ratio, μ or β, is simply the rest mass of the proton (a ... In fact, in the chiral limit, mp is proportional to the QCD energy scale, ΛQCD. At a given energy scale, the ...

2.How is the mass of the electron calculated? ... First, the mass-to-charge ratio was calculated by JJ Thomson in 1897. By firing electrons from a cathode gun at a known velocity, through an electric field of known strength, he was able to observe how much the field deflected the beam.

3.Beam of electrons moving in a circle in a Teltron tube, due to the presence of a magnetic field. Purple light is emitted along the electron path, due to the electrons colliding with gas molecules in the bulb. The mass-to-charge ratio of the electron can be measured in this apparatus by comparing the radius of the purple circle, the strength of the magnetic field, and the voltage on the electron gun. The mass and charge cannot be separately measured this way—only their ration

4. According to particle physics a partical having a mass due to its interaction with higgs field. ... The mass of an atom depend upon sum of mass protons and neutrons and independent of electron because its mass is negligible.
