AIPMT MAIN 2008 Physics Binding Energy MCQ Question
Type: MCQ-conceptual-Medium-Class 12
If M(A; Z), Mₚ and Mₙ denote the masses of the nucleus ᵃX, proton and neutron respectively in units of u (1 u = 931.5 MeV/C²) and BE represents its bonding energy in MeV, then
A
M(A, Z) = ZMₚ + (A - Z)Mₙ + BE/C²
B
M(A, Z) = ZMₚ + (A - Z)Mₙ - BE/C²
C
M(A, Z) = ZMₚ + (A - Z)Mₙ + BE
D
M(A, Z) = ZMₚ + (A - Z)Mₙ - BE
Correct Answer
Option B
Detailed Explanation
The mass of a nucleus is given by M(A, Z) = ZMₚ + (A - Z)Mₙ - BE/C², where BE is the binding energy.
