Q158 / 160 · AP EAMCET 2021 (19 Aug Shift 2) · Physics

Which of the following statement is correct?

Correct answer
A
The rest mass of the stable nucleus is less than the sum of the rest masses of its separated nucleons
B
The rest mass of the stable nucleus is greater than the sum of the rest masses of its separated nucleons
C
In nuclear fission, energy is released by fusion is of two nuclei of medium mass (approximate $100 amu$ )
D
None of these

Solution

The invariant mass, rest mass, intrinsic mass, proper mass, or in the case of bound systems simply mass, is the portion of the total mass of an object or system of objects that is independent of the overall motion of the system.

Hence, the correct answer is option: 'A'.
