7. Mp denotes the mass of a proton and Mn 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)

M(N, Z) = NM_n + ZM_p + B/c²

M(N, Z) = NM_n + ZM_p – Bc²

M(N, Z) = NM_n + ZM_p + Bc²

M(N, Z) = NMn + ZMp – B/c²
