MASS-ENERGY EQUIVALENCE

The question given below consist of an assertion (A) and a reason ( R). Use the following key to choose the appropriate answer to these questions from the codes (a), (b), ( c) and (d) given below: (a) Both A and R are true and R is the correct explanation of A. (b) Both A and R are true but R is NOT the correct explanation of A. (c) A is true but R is false. (d) A is false and R is also false Assertion: In a nuclear process mass gets converted into energy. Reason: According to Einstein's mass energy equivalence relation, mass m is equivalent to energy E, given be the relation E=mc^2 where c is the speed of light in vacuum.

Equivalent Mass

The rest mass of the deuteron, ._1^2 H , is equivalent to an energy of 1876 MeV, the rest mass of a proton is equivalent to 939 MeV and that of a neutron to 940 MeV. A deuteron may disintegrate to a proton and a neutron if it :
