What is the mass of the planet that has a satellite whose time period is `T` and orbital radius is `r`?

Radius of orbit of a satellite is R and T is time period. Find T' when orbit radius increase to 9R

According to Kepler's law of planetary motion, if T represents time period and r is orbital radius, then for two planets these are related as

According to Kepler's law of planetary motion, if T represents time period and r is orbital radius, then for two planets these are related as

If the time period of a satellite in the orbit of radius r around a planet is T. Then the time period of a satellite in orbit of radius 4r is T = .....

The period of revolution of a surface satellite around a planet of radius R is T. The period of another satellite around the same planet in an orbit of radius 3R is
