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 \( \dfrac{20}3 \times 10^{-11} \text{ N m}^{2}\text{/kg}^{2} \).
