Question:medium
If the ratio of the distances of a planet from the sun at perihelion and aphelion is 2: 3, then the ratio of their respective velocities at the perihelion and aphelion is
If the ratio of the distances of a planet from the sun at perihelion and aphelion is 2: 3, then the ratio of their respective velocities at the perihelion and aphelion is
Show Hint
Logic Tip: Velocity and orbital radius are inversely proportional at the apsides (perihelion and aphelion). The planet moves fastest when it is closest to the sun, and slowest when it is furthest. Simply flip the distance ratio to get the velocity ratio!
