The total kinetic energy of the particles.
Answer to Problem 1OQ
Option (c).
Explanation of Solution
In the given decay process, muon decays into an electron, electron antineutrino and a muon neutrino. Here, muon is having greater value of rest mass energy than electron and neutrinos together.
The rest mass energy for muon is 105.7MeV/c2. On the other hand, the electron is having rest mass energy for 0.511MeV/c2 and that for neutrinos is less than 0.3MeV/c2. Thus, muon is having more rest mass energy than others.
Write the expression for the energy.
Here,
Conclusion:
Since, the muon is having more rest mass energy than others. Thus, option (c) is correct.
Since, total kinetic energy is not zero. Thus, option (a) is incorrect.
Since, the muon is not having less rest mass energy than others. Thus, option (b) is incorrect.
Since, the muon is having more rest mass energy than others. Thus, option (d) is incorrect.
