Q. The binding energies per nucleon for a deuteron and an $\alpha -$ particle are $x_{1}$ and $x_{2}$ respectively. What will be the energy $Q$ released in the reaction $\ _{1}H^{2} + \ _{1}H^{2} \rightarrow_{2}He^{4} + Q$
A) $4(x_{1} + x_{2})$
B) $4(x_{2} - x_{1})$
C) $2(x_{1} + x_{2})$
D) $2(x_{2} - x_{1})$
Explanation
(b) $Q = 4(x_{2} - x_{1})$
