A nucleus of mass

\mathrm{214}

amu in free state decays to emit an

\alpha

-particle. Kinetic energy of the

\alpha

-particle emitted is

6.7\,MeV

. The recoil energy (in

MeV

) of the daughter nucleus is

View answer and explanation

Correct option: D

0.125

Option D (0.125) is correct because the recoil energy of the daughter nucleus is calculated using the conservation of momentum.
