The energy released in the fusion of 2 kg2 \mathrm{~kg} of hydrogen deep in the sun is EH\mathrm{E}_{\mathrm{H}} and the energy released in the fission of 2 kg2 \mathrm{~kg} of 235U{ }^{235} \mathrm{U} is EU\mathrm{E}_{\mathrm{U}}. The ratio EHEU\frac{\mathrm{E}_{\mathrm{H}}}{\mathrm{E}_{\mathrm{U}}} is approximately :

(Consider the fusion reaction as 411H+2e−→24He+2v+6γ+26.7 M eV{4}_1^1 \mathrm{H}+2 \mathrm{e}^{-} \rightarrow{ }_2^4 \mathrm{He}+2 \mathrm{v}+6 \gamma+26.7 \mathrm{~M~eV}, energy released in the fission reaction of 235U{ }^{235} \mathrm{U} is 200 M eV200 \mathrm{~M~eV} per fission nucleus and NA=6.023×1023\mathrm{N}_{\mathrm{A}}=6.023 \times 10^{23})
View answer and explanation
Correct option: C
7.62
Option C (7.62) is correct because it is the approximate ratio of energy released in hydrogen fusion to uranium fission, calculated using the given values.
