NEET Physics Mass-Energy Relation MCQ Question
Which of the following statements regarding mass-energy relation and nuclear binding energy is correct?
The mass of a nucleus is always less than the sum of the masses of its individual nucleons due to binding energy.
The binding energy per nucleon increases with the number of nucleons in all nuclei.
Mass and energy are conserved separately in nuclear reactions, as per Einstein's theory.
The binding energy of a nucleus is the energy required to separate it into its nucleons.
Correct Answer
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.
