NEET Physics Orbital Motion MCQ Question
Which of the following statements about orbital motion are correct?
Earth and Mars both move in elliptical orbits around the Sun.
The speed of an object in a circular orbit depends on its distance from the central mass.
The orbital period of a satellite increases as the radius of its orbit increases.
Only natural satellites, like the Moon, follow Kepler's laws of planetary motion.
Correct Answer
Detailed Explanation
Statement B is correct as the speed of an object in a circular orbit is determined by its distance from the central mass, as indicated by the relationship v = √(GM/R). Statements A and C are not explicitly confirmed in the context provided, and D is incorrect since artificial satellites also follow Kepler's laws.
