Question
Mp denotes the mass of the proton and Mn 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)
Options
M (N, Z) = NMn + ZMp – Bc2
M (N, Z) = NMn + ZMp + Bc2
M (N, Z) = NMn + ZMp – B / c2
M (N, Z) = NMn + ZMp + B / c2
Solution
M (N, Z) = NMn + ZMp – B / c2
