M_(p) denotes the mass of the proton and M_(n) denotes mass 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 (where c is the speed of light)

Answer»

<P>`M(N ,Z) = NM_(n) + ZM_(p) - BC^(2)`
`M(N ,Z) = NM_(n) + ZM_(p) + Bc^(2)`
`M(N ,Z) = NM_(n) + ZM_(p) - B/(c^(2))`
`M(N ,Z) = NM_(n) + ZM_(p) + B/(c^(2))`

Answer :C
