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 Mass of fission products \[\Rightarrow \] \[\frac{\text{Mass}\,\text{of}\,\text{fission}\,\text{products}}{\text{Mass}\,\text{of}\,\text{parent}\,\text{nucleus}}\text{}\,\text{1}\] Note: 1. Nuclear fission was discovered by Ottohan and Strassman. 2. In each fission reaction a tremendous amount of energy \[(\approx 190\,Mev)\] is released.
