A stationary nucleus of mass `24` amu emits a gamma photon. The energy of the emitted photon is `7 MeV`. The recoil energy of the nucleus is

A free nucleus of mass 24 amu emits a gamma photon (when initially at rest). The energy of the photon is 7 MeV . The recoil energy of the nucleus in KeV is (Assuming 1 "amu"=931 MeV ).

A nucleus of mass 220 amu in the free state decays to emit an alpha -particle . Kinetic energy of the alpha -particle emitted is 5.4 MeV. The recoil energy of the daughter nucleus is

A nucleus of mass 20 u emits a gamma -photon of energy 6 MeV. If the emission assume to occur when nucleus is free and rest, then the nucleus will have kinetic energy nearest to (take 1u = 1.6 xx 10^(-27) kg)
