Question

A closed system consists of a neutron and a positron. The neutron eventually decays.

Right after decay, what are the most likely particles in the system and what is the charge in the system? (Use the principle of conservation of charge.)

Proton, electron, and antineutrino. The total charge is zero. Proton, electron, antineutrino and positron. The total charge is +e. Proton, positron, and antineutrino. The total charge is +2e. The particles annihilate leaving nothing but a flash of highly energetic radiation. The total charge is zero.

Explanation / Answer

The total charge is conserved

before decay the charge is +e and must be same immediately after decay

the most likely scenario is

Proton, electron, antineutrino and positron. The total charge is +e.
