Physics-Mass-Energy Relation

NEET Physics Mass-Energy Relation MCQ Question

Type: MCQ-numerical-Easy-Class 12

According to Einstein's mass-energy equivalence principle, if the mass defect of a nucleus is 0.13691 u, what is the equivalent energy released in MeV?

A

127.4 MeV

B

126.8 MeV

C

128.5 MeV

D

129.3 MeV

Correct Answer

Option A

Detailed Explanation

The energy equivalent of a mass defect is calculated using E=mc², where 1 u is equivalent to 931.5 MeV. Thus, 0.13691 u corresponds to approximately 127.4 MeV.
