In introductory physics laboratories, a typical Cavendish balance for measuring the gravitational constant G uses lead spheres with masses of 1.90 kg and 19.0 g whose centers are separated by about 2.60 cm. Calculate the gravitational force between these spheres, treating each as a particle located at the center of the sphere.
