Physics-Mass-Energy Relation

NEET Physics Mass-Energy Relation MCQ Question

Type: MCQ-numerical-Medium-Class 12

If a nucleus has a mass defect ΔM\Delta M of 0.01 u, what is the binding energy ΔEb\Delta E_b of this nucleus in MeV? (1 u=931.5 MeV/c2)(1 \text{ u} = 931.5 \text{ MeV/c}^2)

A

9.315 MeV

B

0.09315 MeV

C

93.15 MeV

D

931.5 MeV

Correct Answer

Option A

Detailed Explanation

Using Einstein’s mass-energy relation ΔEb=ΔMc2\Delta E_b = \Delta M c^2, and given ΔM=0.01 u\Delta M = 0.01 \text{ u}, the binding energy is 0.01×931.5 MeV=9.315 MeV0.01 \times 931.5 \text{ MeV} = 9.315 \text{ MeV}.
