Assertion :- After Einstein showed the equivalence of mass and energy \( \mathrm{E}=\mathrm{mc}^{2} \) we cannot any longer speak of separate laws of conservation of mass and conservation of energy.
Reason :- We have to speak of an unified law of
- conservation of mass and energy. The most convincing evidence that this principle operates
- in nature comes from nuclear physics.
