Nuclear Binding energy
Question

In a fission reaction U 92236X  117+Y  117+n+n, the binding energy per nucleon of X and Y is 8.5 MeV where as of U  236 is 7.6 MeV. The total energy liberated will be about

Moderate
Solution

E=8.5 x 234 - 7.6 x 236=195.4 MeV                                                   =200 MeV
