- #17A satellite orbiting a planet with a radius of 2.0 x 107m very near the surface of the planet has a period of 4.1 hours. Determine the gravitational field intensity g on that planet.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. Need Help? Master It Read It
