If $m$ is the mass of the $_Z{X^A}$ nucleus,and $m_n$ and $m_p$ are the masses of a neutron and a proton respectively,then which of the following is correct?

If the binding energy per nucleon of a nuclide is high,then:

The graph shows the binding energy per nucleon versus mass number. $A, B, C, D, E, F$ are different nuclei. Four processes are given where $\varepsilon$ is the energy released. In which process is $\varepsilon > 0$?
$(i) \, A + B \rightarrow C + \varepsilon$
$(ii) \, C \rightarrow A + B + \varepsilon$
$(iii) \, D + E \rightarrow F + \varepsilon$
$(iv) \, F \rightarrow D + E + \varepsilon$

What is nuclear energy? Explain how nuclear energy is released from the curve of binding energy.

The binding energy of a nucleon in a nucleus is of the order of a few

If $M(A, Z)$,$M_p$,and $M_n$ represent the masses of the nucleus ${}_{Z}^{A}X$,proton,and neutron in $u$ units respectively $(1u = 931.5 \, MeV/c^2)$,and $BE$ represents the binding energy in $MeV$,then which of the following relations is correct?
