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 a neutron, respectively, the nuclear binding energy of the isotope is

Options

  1. AM₀ c ^2
  2. B(M₀-17 M_n ) c^2
  3. C(M₀-8 M_p ) c^2
  4. D(8 M_p+9 M_n-M_ O ) c^2

Correct answer

D. (8 M_p+9 M_n-M_ O ) c^2

Step-by-step solution

The binding energy is given as BE = m c^2 where, m= mass defect and C= speed of light BE = (8 M_ p +9 M_ n -M_ O ) c^2
