What happens to the orbital period of an artificial satellite if its orbital radius around the Earth is increased?

💡 Solution & Explanation

According to Kepler's third law of planetary motion, the square of a satellite's orbital period is directly proportional to the cube of its orbital radius, implying that increasing the radius increases the time taken to complete one revolution. Geostationary satellites operate at much higher altitudes and therefore have longer periods than low Earth orbit satellites.
