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.
