Question

During $\beta -decay$ (beta minus), the emission of antineutrino particle is supported by which of the following statement(s)?

• A. Angular momentum conservation holds good in any nuclear reaction.
• B. Linear momentum conservation holds good in any nuclear reaction.
• C. The KE of emitted $\beta -particle$ is varying continuously to a maximum value.
• D. None of the above.

Answer 1

Answer: (A), (B), (C)

Angular momentum conservation holds good in any nuclear reaction.
Linear momentum conservation holds good in any nuclear reaction.
The KE of emitted $\beta -particle$ is varying continuously to a maximum value.

The following principles hold true in any situation in the universe
1. Conservation of linear momentum (if no external force)
2. Conservation of angular momentum (no external moment)
2. Conservation of energy
3. Conservation of charge
