The energy equivalent of one atomic mass unit is:

1. 1.6 × 10⁻¹⁹ J
2. 6.02 × 10²³ J
3. 931 MeV
4. 9.31 MeV

Correct answer: 931 MeV

Solution

The energy equivalent of one atomic mass unit (1 u) is approximately 931 MeV, derived from Einstein's mass-energy equivalence relation, E=mc², where 1 u corresponds to about 1.66 × 10⁻²⁷ kg.
