Einstein’s mass-energy relation emerging out of his famous theory of relativity relates mass (m) to energy (E) as E=`mc^ 2` , where c is the speed of light in vacuum. At the nuclear level, the magnitudes of energy are very small. The energy at nuclear level is usually measured in MeV, where 1MeV=`1.6xx10^−13 J`, the masses are measured in unified atomic mass unit (u) where, `1u=6xx10 ^−27 kg`.
A student writes the relation as 1 u = 931.5 MeV. The teacher points out that the relation is dimensionally incorrent. Write the correct relation.
