A heavy nucleus X of mass number A = 240 and binding energy per nucleon = 7.6 MeV is split into two nearly equal fragments Y and Z of mass numbers A1 = 110 and A2 = 130. The binding energy of each one of these nuclei is 8.5 MeV per nucleon. Calculate the total binding energy of each of the nuclei XY and Z, and hence the energy Q released per fission in MeV.   



Correct option is

(1824, 935, 1105, 216)MeV

The nucleus X has 240 nucleons. So its binding energy is 


The binding energy of nucleus Y is 


The binding energy of nucleus Z is  


 energy released per fission  is
