A) Kinetic energy of striking proton is 17.28 MeV
B) Kinetic energy of striking proton is 8.64 MeV
C) Kinetic energy of striking proton is 4.32 MeV
D) Kinetic energy of striking proton is 2.16 MeV
Correct Answer: A
Solution :
[a] Q value of the reaction \[Q=(2\times 4\times 7.06-7\times 5.6)=17.28\] MeV....(i) \[{{K}_{P}}+Q=2{{K}_{\alpha }}\] .......(ii) \[\sqrt{2{{m}_{P}}{{K}_{p}}}=2\sqrt{2{{m}_{\alpha }}{{K}_{\alpha }}}\cos \alpha \] \[{{K}_{P}}={{K}_{\alpha }}\] ?...(iii) So \[{{K}_{P}}=17.28\text{ }MeV.\]You need to login to perform this action.
