Back to Exercise
Which of the following shows the masses of the three elementary particles in decreasing order?
- A Baryons, Mesons, Leptons Correct
- B Leptons, Baryons, Mesons
- C Leptons, Mesons Baryons
- D Mesons, Baryons, Leptons
Correct Answer: Option A
*leptons are the lighter particles which can participate in week interaction ex-electrons, *baryons are the particles which can participate in both week n strong interactions ex-proton n neutrons. Mesons belong to baryons ex-sigma particles.
∴ Decreasing Order : Baryons, Mesons, Leptons
