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) = NMn + ZMp + B/c2
- M(N, Z) = NMn + ZMp – Bc2
- M(N, Z) = NMn + ZMp + Bc2
- M(N, Z) = NMn + ZMp – B/c2
Correct Option: D
| Mass defect = | c2 |
Mass of nucleus = Mass of proton + mass of neutron – mass defect
