The energy released in the fusion of $\displaystyle 2 k g$ of hydrogen deep in the sun is $\displaystyle E_H$ and the energy released in the fission of $\displaystyle 2$ kg of $\displaystyle { }^{235} \mathrm{U}$ is $\displaystyle E_U$. The ratio $\displaystyle \frac{E_H}{E_U}$ is approximately: (Consider the fusion reaction as $\displaystyle 4{ }_1^1 H+2 \mathrm{e}^{-} \rightarrow{ }_2^4 \mathrm{He}+2 \nu+6 \gamma+26.7 \mathrm{MeV}$, energy released in the fission reaction of $\displaystyle { }^{235} \mathrm{U}$ is $\displaystyle 200$ MeV per fission nucleus and $\displaystyle \mathrm{N}_{\mathrm{A}}=$ $\displaystyle 6.023 \times 10^{23}$ )
