AIPMT PRELIMS 2008 Physics Binding Energy MCQ Question
Type: MCQ-conceptual-Hard-Class 12
If M (A, Z), Mₚ and Mₙ denote the masses of the nucleus ²⁴₁₂X, proton and neutron respectively in units of u (1u = 931.5 MeV/c²) and BE represents its bonding energy in MeV, then -
A
M(A, Z) = ZMₚ + (A - Z)Mₙ - BE
B
M(A, Z) = ZMₚ + (A - Z)Mₙ + BE/c²
C
M(A, Z) = ZMₚ + (A - Z)Mₙ - BE/c²
D
M(A, Z) = ZMₚ + (A - Z)Mₙ + BE
Correct Answer
Option C
Detailed Explanation
The mass defect is related to the binding energy by the equation BE = Δm c², where Δm = ZMₚ + (A - Z)Mₙ - M(A, Z).
