M_P denotes the mass of a proton and M_n that 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):

Options

  1. AM(N, Z)=N M_n+Z M_p-B c^2
  2. BM(N, Z)=N M_n+Z M_p-B c^2
  3. CM(N, Z)=N M_n+Z M_p-B / c^2
  4. DM(N, Z)=N M_n+Z M_p+B / c^2

Correct answer

C. M(N, Z)=N M_n+Z M_p-B / c^2

Step-by-step solution

Binding B= aligned & [N M_n+2 M_P-M (N₁ ^2 ] C^2 . & M (N₁^2 )=N M_n+Z M_P- B C^2 aligned
