A nucleus

{ }_Z^A X

has mass represented by

m(A, Z)

, If

m_p

and

m_n

denote the mass of proton and neutron respectively and BE the binding energy (in

{MeV}

) then.

View answer and explanation

Correct option: B

B E=\left[Z m_p+(A-Z) m_n-m(A, Z)\right] c^2

Option B (

B E=\left[Z m_p+(A-Z) m_n-m(A, Z)\right] c^2

) is correct because the binding energy is the difference between the mass of the individual nucleons and the mass of the nucleus, multiplied by

c^2
