Question 15

The mass of a free proton is mpm_\text{p}mp​, the mass of a free neutron is mnm_\text{n}mn​, and the mass of a carbon-13 (613C^{13}_{6}\text{C}613​C) nucleus is MMM. The speed of light in a vacuum is ccc.

Which expression correctly represents the binding energy per nucleon of the carbon-13 nucleus?

A
(6mp+7mn−M)c213 \frac{(6m_\text{p} + 7m_\text{n} - M)c^2}{13} 13(6mp​+7mn​−M)c2​
B
(7mp+6mn−M)c213 \frac{(7m_\text{p} + 6m_\text{n} - M)c^2}{13} 13(7mp​+6mn​−M)c2​
C
(6mp+7mn−M)c26 \frac{(6m_\text{p} + 7m_\text{n} - M)c^2}{6} 6(6mp​+7mn​−M)c2​
D
(6mp+7mn−M)c2 (6m_\text{p} + 7m_\text{n} - M)c^2 (6mp​+7mn​−M)c2
