# Off Duty

An astronaut on a space walk in deep intergalactic space takes two lead spheres and places them in space, exactly $$2\text{ m}$$ apart. One lead sphere has a mass of $$6\text{ kg}$$ and the other a mass of $$10\text{ kg}$$. What is the gravitational attraction between the spheres in Newtons?

For purposes of this calculation, assume a value for $$G$$ of $$\dfrac{20}3 \times 10^{-11} \text{ N m}^{2}\text{/kg}^{2}$$.
