A $1\mathrm{.}0$ kg mass is located at the origin. A second, $1\mathrm{.}0$ kg mass is located at position $(-8,3)$ m$.$ They both experience equal and opposite gravitational forces towards each other. The magnitude of the universal gravitational force vector is given by F$=$Gm$1$m$2/$r$^2$ G is the Gravitational Constant, m$1$ and m$2$ are the masses, and r is the distance between the two mssses.
