A) less than 1
B) greater than 1
C) equal to 1
D) depends on the mass of parent nucleus
Correct Answer: A
Solution :
In fission process, when a parent nucleus breaks into daughter products, then some mass is lost in the form of energy. Thus, mass of fission products < mass of parent nucleus \[\Rightarrow \] \[\frac{Mass\text{ }of\text{ }fission\text{ }products}{Mass\text{ }of\text{ }parent\text{ }nucleus}\] Note: 1. Nuclear fission was discovered by Ottohan and Strassman. In each fission reaction a tremendous amount of energy (\[\approx \]190 MeV) is released.
