Gravitation

Question

Two satellite A and B go round a planet in circular orbits having radii 4R and R respectively. If the speed of … is …, the speed of … will be :

Accepted Answer

Option A. To solve this question, we will use the fact that for an object in a circular orbit, the centripetal force required to keep the object in orbit is provided by the gravitational force between the object and the planet it is orbiting. This principle gives us the relationship between the speed of the satellite, its orbital radius, and the mass of the planet.
