If a negative muon decays to form an electron-antineutrino pair and one other particle,the other particle may be a(n)
A)positron.
B)antineutrino.
C)mu neutrino.
D)electron.

Question

Quizplus · Accepted Answer

In the decay of a negative muon, a muon neutrino is always produced along with the electron-antineutrino pair. Therefore, the other particle must be a mu neutrino (which is a type of neutrino). Choices A, B, and D are not possible as they are either matter particles (positron and electron) or their respective antiparticles (antineutrino).
