Solution
Correct Answer:
Δmc2
According to Einstein's mass-energy equivalence principle, mass can be converted into energy. The energy (E) released or absorbed in a nuclear process is directly related to the change in mass (Δm) by the equation E=Δmc2, where c is the speed of light in a vacuum (3×108m/s).
This hard difficulty physics question is from the chapter atoms and nuclei, covering the topic of mass-energy conversion. It appeared in the 2025 exam.
