Answer Key / Explanation : (b) -

(b)

1. False. The neutrino has zero charge and seems to have rest mass equal to zero. It is emitted along with the emission of a position (positive charge of +1e and mass equal to electron). For example

Antineutrino is emitted along with the emission of -particle

2. True. The expression of magnetic moment is

3. False

4. False. The correct expression is
