Vedclass · Answer

(A) In a nuclear decay process, energy is released because the total mass of the products is less than the mass of the parent nucleus. This mass difference, known as the mass defect $(\Delta m)$, is converted into energy according to Einstein's mass-energy equivalence principle, $E = \Delta m c^2$.Since energy is released, the total rest mass energy of the products must be less than the rest mass energy of the parent nucleus to satisfy the law of conservation of energy.Therefore, both the Assertion and the Reason are correct, and the Reason provides the correct explanation for the Assertion.

Assertion : In a decay process of a nucleus, the mass of products is less than that of the parent.
Reason : The rest mass energy of the products must be less than that of the parent.
