In introductory physics laboratories, a typical Cavendish balance for measuring the gravitational constant G uses lead spheres with masses of $1\mathrm{.}60$ kg and $16\mathrm{.}0$ g whose centers are separated by about $3\mathrm{.}80$ cm$.$ Calculate the gravitational force between these spheres, treating each as a particle located at the center of the sphere.
