SUMMARY

The discussion focuses on calculating the gravitational force between two lead spheres using Newton's Law of Universal Gravitation. The spheres have masses of 1.8 kg and 13.9 g, with their centers separated by 5.77 cm. The gravitational constant G is specified as 6.67259 x 10^-11 N m^2/kg^2. A correction was noted regarding the power of ten for G, emphasizing the importance of accuracy in scientific calculations.

PREREQUISITES

In introductory physics laboratories, a typical
Cavendish balance for measuring the gravita-
tional constant G uses lead spheres of masses
1.8 kg and 13.9 g whose centers are separated
by 5.77 cm.
Calculate the gravitational force between
these spheres, treating each as a point mass
located at the center of the sphere. Use G =
6.67259 x 10^11 N m^2/kg^2.

Do you know how to determine the gravitational force between two bodies using Newton's Law of Universal Gravitation?

Your G is wrong, the power of 10 should be -11.
