Which of the following is correct regarding binding enegry of nucleus?A. The nucleons are bound together in a nucleus and energy must be supplied to the nucleus to separate the consituent nucleons to large distance. The amount of energy needed to do this is called the binding enegry o fthe nucleus. If the nucleons are initially well separated and are brought to from the nucleus, this much energy is released `B.E. = Deltamc^(2), Deltam:` mass defect `B.E. = (Zm_(p)+Nm_(n) -M)c^(2)`B. `B.E.//`nucleon is maximum for `._(26)Fe^(56)`, hence iron is most stable elementC. For a nuclear reaction, `alpha`-value of the reaction is the difference between the rest mass enegry of the initial consituents and that of the final products `Q =U_(i) -U_(f)` `A+B rarr C+D` `Q-`value `={(m_(A) +m_(B)) - (m_(C) +m_(D))}c^(2)`D.
