The time period of a satellite orbiting a celestial body (like Earth) is related to the radius of its orbit. According to Kepler's Third Law and Newtonian gravitation, a larger orbital radius implies a longer orbital period (time to complete one orbit). This is because the satellite has to travel a greater distance, and the gravitational force pulling it towards the Earth is weaker at higher altitudes, resulting in a slower orbital speed.
As the height of satellite above earth surface increases, the time taken to complete the orbit -
