Vedclass · Answer

(C) The energy released in a nuclear decay is given by the difference between the total binding energy of the products and the total binding energy of the parent nucleus.Total binding energy of the parent nucleus = $200 	imes 6.5 	ext{ MeV} = 1300 	ext{ MeV}$.Total binding energy of the daughter nuclei = $(80 	imes 7 	ext{ MeV}) + (120 	imes 8 	ext{ MeV}) = 560 	ext{ MeV} + 960 	ext{ MeV} = 1520 	ext{ MeV}$.Energy released = (Total binding energy of products) - (Total binding energy of parent) = $1520 	ext{ MeV} - 1300 	ext{ MeV} = 220 	ext{ MeV}$.

$M_n$ and $M_p$ represent the mass of a neutron and a proton, respectively. If an element having atomic mass $M$ has $N$ neutrons and $Z$ protons, then the correct relation is:

$A$ nucleus of mass $ 20 u $ emits a $ \gamma $ photon of energy $ 6 MeV $. If the emission is assumed to occur when the nucleus is free and at rest, then the nucleus will have a kinetic energy nearest to (take $ 1 u = 1.6 \times 10^{-27} kg $): (in $keV$)
