In a fission reaction ${ }_{92}^{236} U \rightarrow{ }^{117} X+{ }^{117} Y+n+n$, the binding energy per nucleon of X and Y is 8.5 MeV whereas of ${ }^{236} U$ is 7.6 MeV. The total energy liberated will be about |
200 KeV 2 MeV 200 MeV 2000 MeV |
200 MeV |
$\Delta E=8.5 \times 234-7.6 \times 236$ = 195.4 MeV = 200 MeV |
