M p denotes the mass of a proton and M 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) M(N, Z) = NM n + ZM p + B/c 2 (b) M(N, Z) = NM n + ZM p - Bc 2 (c) M(N, Z) = NM n + ZM p + Bc 2 (d) M(N, Z) = NM n + ZM p – B/c 2



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)


(a)    M(N, Z) = NMn + ZMp + B/c2


(b)    M(N, Z) = NMn + ZMp - Bc2


(c)    M(N, Z) = NMn + ZMp + Bc2


(d)    M(N, Z) = NMn + ZMp – B/c2
