If `M_(o)` is the mass of an oxygen isotope `._(8)O^(17), M_(p)` and `M_(N)` are the masses of a proton and neutron respectively, the nuclear binding energy of the isotope is:

Options

A. `(M_(o)-8M_(p))c^(2)`
B. `(M_(o)-8M_(p)-9M_(n))c^(2)`
C. `M_(o)c^(2)`
D. `(M_(o)-17M_(n))c^(2)`

Answer

B

Explanation

Binding energy,
`BE=(M_("nucleus")-M_("nucleous"))c^(2)`
`=(M_(o)-8M_(p)-9M_(n))c^(2)`
