Physics-Mass-Energy Relation
NEET Physics Mass-Energy Relation MCQ Question
Type: MCQ-conceptual-Easy-Class 12
Which of the following statements regarding mass-energy relation and nuclear binding energy is correct?
A
The mass of a nucleus is always less than the sum of the masses of its individual nucleons due to binding energy.
B
The binding energy per nucleon increases with the number of nucleons in all nuclei.
C
Mass and energy are conserved separately in nuclear reactions, as per Einstein's theory.
D
The binding energy of a nucleus is the energy required to separate it into its nucleons.
Correct Answer
Option A
Detailed Explanation
The mass of a nucleus is indeed less than the sum of the masses of its constituents due to the binding energy, which causes a mass defect. This is illustrated in the context of the oxygen nucleus example where the mass defect is noted.
