Force between two ships

Two ships, each of mass $5.0\cdot 10^7\mathrm{kg}$, have their centers of mass at a distance $d=1.0\cdot 10^2\mathrm{m}$. Treating them as point masses, compute the magnitude of the gravitational force with which they attract each other ($G=6.67\cdot 10^{-11}\mathrm{N}\cdot {\mathrm{m}}^2/k{\mathrm{g}}^2$).
