Vedclass · Answer

(C) In a nuclear fusion reaction,two lighter nuclei combine to form a heavier nucleus.For the reaction to be energetically favorable and spontaneous,the total binding energy of the product nucleus must be greater than the sum of the binding energies of the reactant nuclei.Here,two nuclei of $A$ (each with binding energy $E_1$) combine to form one nucleus of $B$ (with binding energy $E_2$).The total binding energy of the reactants is $2E_1$.The binding energy of the product is $E_2$.For the reaction to occur,the product must be more stable,meaning its binding energy must be higher than the total binding energy of the reactants.Therefore,the condition is $E_2 > 2E_1$.

Let $E_1$ and $E_2$ be the binding energies of two nuclei $A$ and $B.$ It is observed that two nuclei of $A$ combine together to form a $B$ nucleus. This observation is correct only if
