Q. In any fission process the ratio (mass of fission products/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
Explanation
[Solution from source] Fission releases energy Q = Δm c², which comes from a loss of mass, so the products are lighter than the parent nucleus and the ratio is less than 1. 'Equal to 1' ignores the mass defect. Answer (1).
