Q. Consider the following factors regarding a satellite maintaining its orbital position around the Earth:

1. Distance from the Earth
2. Tangential speed of the satellite
3. Earth's radius
4. Gravitational force of the Earth
5. Mass of the satellite
6. Size of the satellite

Which of the above determine the balance of centripetal force and gravitational attraction enabling stable orbit?
Answer: 1, 2, 3 and 4
Notes: The stable orbital motion of a satellite is governed by the distance from the Earth, the tangential speed of the satellite, Earth's radius, and the gravitational force of the Earth. The mass and size of the satellite are not factors in this specific balance because gravitational and centripetal forces act proportionally to mass, and size is irrelevant to the orbital mechanics as per Newtonian gravitation.
