# NEET Physics Nuclei Questions Solved

${\mathrm{M}}_{\mathrm{p}}$ denotes the mass of a proton and ${\mathrm{M}}_{\mathrm{n}}$ that of a neutron. A given nucleus, of binding energy B, contains Z protons and N neutrons. The mass M(N, Z) of the nucleus is given by (c is the velocity of light)
(a) $\mathrm{M}\left(\mathrm{N},\mathrm{Z}\right)={\mathrm{NM}}_{\mathrm{n}}+{\mathrm{ZM}}_{\mathrm{p}}-{\mathrm{Bc}}^{2}$
(b) $\mathrm{M}\left(\mathrm{N},\mathrm{Z}\right)={\mathrm{NM}}_{\mathrm{n}}+{\mathrm{ZM}}_{\mathrm{p}}+{\mathrm{Bc}}^{2}$
(c) $\mathrm{M}\left(\mathrm{N},\mathrm{Z}\right)={\mathrm{NM}}_{\mathrm{n}}+{\mathrm{ZM}}_{\mathrm{p}}-\mathrm{B}/{\mathrm{c}}^{2}$
(d) $\mathrm{M}\left(\mathrm{N},\mathrm{Z}\right)={\mathrm{NM}}_{\mathrm{n}}+{\mathrm{ZM}}_{\mathrm{p}}+\mathrm{B}/{\mathrm{c}}^{2}$
