A heavy nucleus

\mathrm{X}

of mass number 240 and binding energy per nucleon

7.6 \mathrm{~MeV}

is split into two fragments

\mathrm{Y}

and

\mathrm{Z}

of mass numbers 110 and 130. The binding energy of nucleons in

\mathrm{Y}

and

\mathrm{Z}

is 8.5

\mathrm{MeV}

per nucleon. Calculate the energy

\mathrm{Q}

released per fission in

\mathrm{MeV}

View answer and explanation

Correct option: D

216 \mathrm{~MeV}

Option D (216 MeV) is correct because the energy released is the difference between the binding energies of the products and the reactant.
