NEET Physics Orbital Motion Assertion Reason Question
Assertion (A): The time period of a satellite orbiting the Earth depends on the mass of the satellite. | Reason (R): Kepler's third law relates the square of the orbital period of a planet to the cube of the semi-major axis of its orbit.
Both A and R are true and R is the correct explanation of A.
Both A and R are true but R is not the correct explanation of A.
A is true but R is false.
A is false but R is true.
Correct Answer
Detailed Explanation
The time period of a satellite is independent of its mass, as described by Kepler's laws. Kepler's third law relates the orbital period to the orbital radius, not the mass of the satellite.
