Problem

The mass of a deuteron (

^{2}_{1}\mathrm{H}

nucleus) is

3.3436\times10^{-27}\,\text{kg}

. The masses of a free proton and neutron are

1.6726\times10^{-27}\,\text{kg}

and

1.6749\times10^{-27}\,\text{kg}

respectively. Find the binding energy of the deuteron in joules.

\bigl(c=3.0\times10^{8}\,\text{m s}^{-1}\bigr)

5.8\times10^{-13}\,\text{J}

3.5\times10^{-12}\,\text{J}

3.5\times10^{-13}\,\text{J}

3.5\times10^{-14}\,\text{J}
