Question

The binding energies per nucleon for a deuteron and an α-particle are x₁ and x₂ respectively. The energy Q released in the reaction

Answer 1

The correct option is (b).

Explanation:

Number of nucleon on reactant side = 4

Binding energy for one nucleon = x₁ 

Binding energy for 4 nucleons = 4x₁ 

Similarly on product side binding energy = 4x₂ 

Now, Q = change in binding energy = 4(x₂ - x₁).
