Q. The binding energies of nuclei $X$ and $Y$ are $E_{1}$ and $E_{2}$, respectively. Two atoms of $X$ fuse to give one atom of $Y$ and an energy $Q$ is released. Then,

Nuclei

Solution:

During fusion, binding energy of daughter nucleus is always greater than the total binding energy of the parent nuclei. The difference of binding energies is released. Hence,
$Q=E_{2}-2 E_{1}$
