Question

In introductory physics laboratories, a typical Cavendish balance for measuring the gravitational constant G uses lead spheres of masses 1.79 kg and 16.9 g whose centers are separated by 5.49 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 × 10−11N · m2/kg2.

Answer 1

That is simply a matter of computing

G*M1*M2/R^2

They have told you what all the terms are. Do the calculation.
