IntermediateMCQProportional Analysis23.1k
A diagram showing a planet at the center with two concentric dashed circles representing the orbits. Satellite A is on the inner dashed circle with radius R. Satellite B is on the outer dashed circle with radius 4R.
Two satellites in circular orbits of different radii around a planet.
Two satellites, Satellite A and Satellite B, are in circular orbits around the same planet of mass \(M\). The radius of the orbit for Satellite A is \(R\), and the radius of the orbit for Satellite B is \(4R\). If both satellites are only influenced by the gravitational force of the planet, what is the ratio of the orbital speed of Satellite A to the orbital speed of Satellite B, \(v_A / v_B\)?
