NEET Physics Nuclei Questions Solved

NEET - 2008

If M A,Z, Mp and Mn denote the masses of the nucleus XZA, proton and neutron respectively in units of u 1 u=931.5 MeV/c2 and BE represnts its binding energy in MeV, then 

(a) M(A,Z)=ZMp+A-ZMn-BE/c2
(b) M(A,Z)=ZMp+A-ZMn+BE

(c) M(A,Z)=ZMp+A-ZMn-BE

(d) M(A,Z)=ZMp+A-ZMn+BE/c2

Binding energy of a nucleus containing N neutrons and Z protons is BE=NMn+ZMp-MA,Zc2    BEc2=NMn+ZMp-MA,Z     BEc2=A,ZMn+ZMp-MA,Z           as N=A-ZM A,Z=ZMp+A-ZMn-BE/c2
