STANDARD Physics Binding Energy MCQ Question
Type: MCQ-numerical-Medium
If the binding energy per nucleon of deuterium is 1.115 MeV, its mass defect in atomic mass unit is
A
0.0048
B
0.0024
C
0.0012
D
0.0006
Correct Answer
Option B
Detailed Explanation
Binding energy per nucleon is Eᵦ = Eₙ/A. For deuterium, A = 2. Thus, 1.115 MeV = Eₙ/2 = 1.115 MeV. As Eᵦ = ΔMc², mass defect, ΔM = 2×1.115/931.5 = 0.0024u.
