# NEET Physics Nuclei Questions Solved

${\mathrm{M}}_{\mathrm{n}}$ and ${\mathrm{M}}_{\mathrm{P}}$ represent mass of neutron and proton respectively. If an element having atomic mass M has N-neutron and Z-proton, then the correct relation will be

(a) $\mathrm{M}<\left[{\mathrm{NM}}_{\mathrm{n}}+{\mathrm{ZM}}_{\mathrm{p}}\right]$          (b) $\mathrm{M}>\left[{\mathrm{NM}}_{\mathrm{n}}+{\mathrm{ZM}}_{\mathrm{p}}\right]$
(c) $\mathrm{M}=\left[{\mathrm{NM}}_{\mathrm{n}}+{\mathrm{ZM}}_{\mathrm{p}}\right]$          (d) $\mathrm{M}=\mathrm{N}\left[{\mathrm{M}}_{\mathrm{n}}+{\mathrm{M}}_{\mathrm{p}}\right]$
