Vedclass · Answer

(A) In a nuclear fusion reaction, the mass of the product nucleus $(m)$ is always less than the sum of the masses of the reactant nuclei $(X+Y)$.This difference in mass, known as the mass defect $(\Delta M = (X+Y) - m)$, is converted into energy according to Einstein's mass-energy equivalence principle, $E = \Delta M c^2$.Therefore, since energy is liberated, the mass must decrease, implying $X+Y > m$.

When two nuclei of mass $X$ and $Y$ respectively fuse to form a nucleus of mass $m$ along with the liberation of some energy, then
