The speed of daughter nuclei is

1. c Δm/(M + Δm)
2. c √(2Δm/M)
3. c √(Δm/M)
4. c √(Δm/(M + Δm))

Correct answer: c √(2Δm/M)

Solution

The correct option relates to the kinetic energy released during nuclear reactions, where the speed of the daughter nuclei is derived from the mass-energy equivalence principle, showing that the kinetic energy is proportional to the mass defect and inversely related to the total mass.
