In introductory physics laboratories, a typical Cavendish balance for measuring the gravitational constant G uses lead spheres with masses of 1.60 kg and 16.0 g whose centers are separated by about 3.30 cm. Calculate the gravitational force between these spheres, treating each as a particle located at the center of the sphere.

The value is  

Explanation:

From the question we are told that

     The mass  of the first lead sphere is

      The mass of the second lead sphere is  

      The separation between masses is  

Generally the gravitational force between each sphere is mathematically represented as

Here G is the gravitational constant with value
