Define the time period of a satellite

Which of the following graphs is true for the motion of a satellite revolving round the Earth. ('T" is the time period of a satellite and 'r' is the distance of the satellite from the Earth).

A satellite in equatorial plane is rotating in the direction of earth's rotation with time interval between its two consecutive appearence over head of an observer as time period of rotation of the earth, T_(E) . What is the time period of the satellite?

According to Kepler’s law the time period of a satellite varies with its radius as

If rho is the density of the planet , the time period of nearby satellite is given by

A small satellite revolves round a planet in an orbit just above planet's surface. Taking the mean density of planet as rho , calculate the time period of the satellite.

The time period of a satellite of earth is 8 hours. If the separation between the earth and the satellite is increased to two times the pervious value, find the new time period of the satellite.

The time period of a satellite of the earth is 10 hours. If the separations between the earth and the satellite is increased to 4 times the previous value, then what will be the new time period of the satellite ?

The time period of the satellite of the earth is 5 hours. If the separation between the earth and the satellite is increased to 4 times the previous value,then what will be the new time period of the satellite ?
