A) \[0.51\,\,MeV\]
B) \[7.10\,\,MeV\]
C) \[6.30\,\,MeV\]
D) \[5.4\,\,MeV\]
Correct Answer: A
Solution :
[a] \[_{0}^{1}n\xrightarrow{{}}_{1}^{1}H{{+}_{-1}}{{e}^{0}}+\bar{v}+Q\] The mass defect during the process \[\Delta m={{m}_{n}}-{{m}_{H}}-{{m}_{e}}=1.6725\times {{10}^{-27}}\] \[-(1.6725\times {{10}^{-27}}+9\times {{10}^{-31}}kg)\] \[=-9\times {{10}^{-31}}kg\] The energy released during the process \[E=\Delta m{{c}^{2}}\] \[E=9\times {{10}^{-31}}\times 9\times {{10}^{16}}=81\times {{10}^{-15}}\] Joules \[E=\frac{81\times {{10}^{-15}}}{1.6\times {{10}^{-19}}}=0.511\,\,MeV\]
