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 - (Given : c is the velocity of light)
A
M (N, Z) = NMn + ZMp + Bc2
B
M(N, Z) = NMn + ZMp – B/c2
C
M(N, Z) = NMn + ZMp + B/c2
D
M(N, Z) = NMn + ZMp – Bc2
Answer
M(N, Z) = NMn + ZMp – B/c2
Explanation
Solution
B.E. = [ Z Mp + (A – Z) Mn – M] c2
M = Z Mp + N Mn –
