In introductory physics laboratories, a typicalCavendish balance for measuring the gravitational constant G uses lead spheres of masses2.21 kg and 22.2 g whose centers are separatedby 5.22 cm.Calculate the gravitational force betweenthese spheres, treating each as a point masslocated at the center of the sphere. Thevalue of the universal gravitational constantis 6.67259 × 10−11N · m2/kg2.Answer in units of N
