If mass of U235=235.12142  amu, mass of U236=236.1205  amu and mass of neutron = 1.008665 amu, then the energy required to remove one neutron from the nucleus U236  is  about

a
75 MeV
b
9 MeV
c
1 eV
d
Zero

detailed solution

Correct option is B

(2)Energy required= Final rest mass energy - Initial rest mass energy= (235.12142 + 1.008665) - 236.1205] x 931 MeV= 0.009585 x 931 MeV=8.92   MeV  ≃   9 MeV.
