Physics Question from JEE Main 2024 · 29 January, Shift 1

The explosive in a Hydrogen bomb is a mixture of 12H^2_1\text{H}, 13H^3_1\text{H}, and 36Li^6_3\text{Li} in some condensed form. The chain reaction is given by:

36Li+01n24He+13H^6_3\text{Li} + ^1_0\text{n} \rightarrow ^4_2\text{He} + ^3_1\text{H} 12H+13H24He+01n^2_1\text{H} + ^3_1\text{H} \rightarrow ^4_2\text{He} + ^1_0\text{n}

[Given: M(Li)=6.01690M(\text{Li}) = 6.01690 amu, M(12H)=2.01471M\left(^{2}_{1}\text{H}\right) = 2.01471 amu, M(24He)=4.00388M\left(^{4}_{2}\text{He}\right) = 4.00388 amu, and 11 amu =931.5= 931.5 MeV] During the explosion, the energy released is approximately:
