For atomic nuclei, the binding energy per nucleon

Statement-1:In a spontaneous fission reaction a heavy nucleus is split into two medium sized ones, each of the new nuclei will have more binding energy per nucleon than the original nucleus Statement-2:Joining two light nuclei together to give a single nucleus of medium size means more binding energy per nucleon in the new nucleus .

Choose the correct from the following. A) Large mass number nuclei undergo fission B) Low mass number nuclei undergo fusion C) For heavy nuclei the decrease in binding energy per nucleon shows the contribution of the increasing coulomb repulsion.

In the process of fission, the binding energy per nucleon

The binding energy per each nucleon in the neighborhood of medium nuclei is 8.5 MeV and the binding energy per each nucleon is about 7.6 MeV and the neighborhood of Uranium. The energy released in the fission of U ^(236) is
