Einstein’s mass -

Answer :

(a) By using Einstein’s mass energy relationship we have,


For one atomic mass unit m = 1 u = 1.67 x 10-27 kg.


Therefore, the energy equivalent,



Or



(b) Given:


Incorrect relation 1 u = 931.5 MeV


Frome Einstein’s equation we have,




For, m = 1 u , E = 931.5 MeV



Therefore, the dimensionally correct relation would be
