An artificial satellite is in a circular orbit around a planet of radius r= 2.05 x103 km at a distance d 310.0 km from the planet's surface. the period of revolution of the satellite around the planet is t 1.15 hours. what is the average density of the planet?

Explanation:

As we know that the satellite revolves around the planet then the centripetal force for the satellite is due to gravitational attraction force of the planet

So here we will have

here we have

here we have

now we can find time period as

Now the density is given as

it may be wrong but i think its a
