Question

A nucleus $_Z^AX$ 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,

• A. BE = [m(A, Z) - Zmp - (A - Z)mn]C2
• B. BE = [Zmp+ (A - Z)mn - m(A, Z)]C2
• C. BE = [Zmp + Amn - m(A, Z)]C2
• D. BE = m(A, Z) - Zmp - (A - Z)mn

Answer 1

Answer: (B)

BE = [Zmp+ (A - Z)mn - m(A, Z)]C2

Answer 2

The correct option is (B): BE = [Zmp+ (A - Z)mn - m(A, Z)]C2.
