A spherical.cavity is made inside a sphere of density, d. If
its centre lies at a distance l, from the centre of sphere,
show that the gravitational strength, I, of the field inside
the cavity is = (4/3) x n G I d.
In introductory physics laboratories, a typical Cavendish balance for measuring the gravitational constant G uses lead spheres with masses of 1.20 kg and 12.0 g whose centers are separated by about
4.90 cm. Calculate the gravitational force between these spheres, treating each as a particle located at the center of the sphere.
