Physics-Mass-Energy Relation
NEET Physics Mass-Energy Relation MCQ Question
Type: MCQ-numerical-Easy-Class 12
Given that the atomic mass unit (u) is defined as 1/12th of the mass of the carbon-12 atom, and using the relation E = mc², calculate the energy equivalent of 1 u in MeV using c = 3 × 10^8 m/s.
A
931 MeV
B
825 MeV
C
1000 MeV
D
750 MeV
Correct Answer
Option A
Detailed Explanation
The mass of 1 u is 1.660539 × 10^-27 kg. Using E = mc², the energy equivalent is E = 1.660539 × 10^-27 kg × (3 × 10^8 m/s)², which converts to approximately 931 MeV.
