Q. Pick out the incorrect statement from the following
A) $\beta$-emission from the nucleus is always accompanied with a neutrino
B) The energy of the $\alpha$-particle emitted from a given nucleus is always constant
C) $\gamma$-ray emission makes the nucleus more stable
D) Nuclear force is charge-independent
Explanation
(a) $\beta^{-}$ emission from the nucleus is always accompanied with a antineutrino
The $\beta^{-}$ decays is $n \rightarrow p + \ e^{-}\ \ \ \ \ \ \ + \ \ \ \ \ \ \overline{v}$
$electron$ $antineutrino$
