In introductory physics laboratories, a typical
Cavendish balance for measuring the gravitational constant G uses lead spheres of masses
1.27 kg and 18.4 g whose centers are separated
by 5.05 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

Two balls, each with a mass of 0.803 kg,
exert a gravitational force of 8.27 × 10
on each other.
How far apart are the balls? The value
of the universal gravitational constant is
6.673 × 10
