AIPMT PRELIMS 2007 Physics Binding Energy MCQ Question
Type: MCQ-conceptual-Hard-Class 12
A nucleus ²⁴₁₁X has mass represented by M(A, Z). If Mₚ and Mₙ denote the mass of proton and neutron respectively and B.E. the binding energy in MeV, then
A
B.E. = [ZMₚ + (A – Z)Mₙ – M(A, Z)]c²
B
B.E. = [ZMₙ + ZMₚ – M(A, Z)]c²
C
B.E. = M(A, Z) – ZMₚ – (A – Z)Mₙ
D
B.E. = [M(A, Z) – ZMₚ – (A – Z)Mₙ]c²
Correct Answer
Option A
Detailed Explanation
The binding energy is calculated using the mass defect, which is the difference between the mass of the nucleus and the sum of the masses of its constituent protons and neutrons.
