Question

In any fission process, ratio of mass of daughter nucleus to mass of parent nucleus is

• A. less than 1
• B. greater than 1
• C. equal to 1
• D. depends on the mass of parent nucleus

Answer 1

Answer: (A)

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.
$\Rightarrow \frac{\text{ Mass of fission products }}{\text{ Mass of parent nucleus }}<1$
