In introductory physics laboratories, a typical Cavendish balance for measuring the gravitational constant G uses lead spheres of masses 0.76 kg and 13.6 g whose centers are separated by 5.08 cm. Calculate the gravitational force between these spheres, treating each as a point mass located at the center of the sphere. The value of the universal gravitational constant is 6.67259 × 10−11 N · m2 /kg2 . Answer in units of N.
