A) 0.73 MeV
B) 7.10 MeV
C) 6.30 MeV
D) 5.4 MeV
Correct Answer: A
Solution :
\[_{0}{{n}^{1}}{{\to }_{1}}{{H}^{1}}{{+}_{-1}}{{e}^{0}}+\overline{v}+Q\] \[\Delta m={{m}_{n}}-{{m}_{\alpha }}-{{m}_{e}}\] \[=(1.6725\times {{10}^{-27}}-1.6725\times {{10}^{-27}}-9\times {{10}^{-31}})kg\] \[=-9\times {{10}^{-31}}kg\]s Energy \[=9\times {{10}^{-31}}\times {{(3\times {{10}^{8}})}^{2}}\] \[=0.511\] MeV Which is nearly equal to 0.73 Mev but as energy will be required. since mass is increasing so answer \[=-0.511\] Mev either (a) or bonus.
