Question

M_p 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):

पर्याय

• 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) = NM_n + ZM_p − B/c²

Answer 1

M(N, Z) = NM_n + ZM_p − B/c²

Explanation:

Now mass defect is Binding Energy/c²

Mass of nucleus = Mass of proton + mass of neutron − mass defect
