NEET Physics Nuclei Questions Solved


The masses of neutron and proton are 1.0087 a.m.u. and 1.0073 a.m.u. respectively. If the neutrons and protons combine to form a helium nucleus (alpha particles) of mass 4.0015 a.m.u. The binding energy of the helium nucleus will be (1 a.m.u.= 931 MeV)

(a) 28.4 MeV               (b) 20.8 MeV
(c) 27.3 MeV               (d) 14.2 MeV

(a) B.E. = mc2=21.0087+1.0073-4.0015=28.4 MeV
