Question
The rings of Saturn are composed of chunks of icethat orbit the planet. The inner radius of the rings is 71000 km,while the outer radius is 166000 km. Find the period of an orbitingchunk of ice at the inner radius. The mass of Saturn is5.69x1026 kg.Find the period of an orbiting chunk of ice atthe outer radius.

Find the period of an orbiting chunk of ice atthe outer radius.
Explanation / Answer
T2 =42r3/Gm T=42r3/Gm Inner ring's period: T=42(7.1e7)3 / (6.67e-11 x5.69e26) T = 19295.2 seconds. Outer ring's period T = 42(1.66e8)3 / (6.67e-11 x5.69e26) T = 68979.96 seconds
