A) 4.8 MeV
B) 5.4 MeV
C) 5.5 MeV
D) 6.8 MeV
Correct Answer: B
Solution :
Q-value of the reaction is 5.5 MeV i.e., \[{{K}_{1}}+{{K}_{2}}=5.5.\] MeV ... (i) By conservation of linear momentum \[{{p}_{1}}={{p}_{2}}\] \[\Rightarrow \] \[\sqrt{2(216){{K}_{1}}}=\sqrt{2(4){{K}_{2}}}\] \[{{K}_{2}}=54\,{{K}_{1}}\] ... (ii) On solving Eqs. (i) and (ii), we get The energy of emitted a-particle \[{{K}_{2}}=5.4\,MeV\]You need to login to perform this action.
