AIPMT PRELIMS 2001 Physics Nuclear Mass and Binding Energy MCQ Question
Type: MCQ-conceptual-Medium-Class 12
Mₙ and Mₚ represent the mass of neutron and proton respectively. An element having mass M has N neutron and Z⁻protons, then the correct relation will be:
A
M < (N.Mₙ + Z.Mₚ)
B
M > (N.Mₙ + Z.Mₚ)
C
M = (N.Mₙ + Z.Mₚ)
D
M = N.Mₙ + Mₚ
Correct Answer
Option A
Detailed Explanation
The mass of an element is slightly less than the sum of the masses of its protons and neutrons due to the binding energy of the nucleus.
