IntermediateMCQProportional Analysis19.2k
A physics diagram showing a planet at the center with radius R. Draw two concentric dashed circular orbits around it. The inner orbit is at distance 2R from the center and has a satellite labeled v1 with a tangential velocity arrow. The outer orbit is at distance 4R from the center and has a satellite labeled v2 with a tangential velocity arrow. Label the planet radius as R from center to surface. Clean textbook-style diagram, minimal background, clear spacing.
Two satellites in circular orbits at different altitudes above a planet.
A satellite of mass \(m\) orbits a planet of mass \(M\) and radius \(R\) in a circular path at an altitude \(R\) above the planet's surface with speed \(v_1\). A second satellite of mass \(2m\) orbits the same planet in a circular path at an altitude \(3R\) above the planet's surface with speed \(v_2\). What is the ratio \(\dfrac{v_1}{v_2}\)?
