NEET Physics Kepler's Laws MCQ Question
Which combination of statements accurately describes Kepler's Laws?
Kepler's laws apply only to circular orbits and do not pertain to elliptical paths.
The first law states that planets move in ellipses with the Sun at one focus, while the second law indicates that a line segment joining a planet and the Sun sweeps out equal areas in equal times.
The third law relates the square of the orbital period of a planet to the cube of the semi-major axis of its orbit, which is applicable to all celestial bodies.
Kepler's laws were developed independently of Newton's laws of motion and gravitation.
Correct Answer
Detailed Explanation
Statement B accurately reflects Kepler's laws, emphasizing the elliptical orbits and the equal area law. Statement A is incorrect as Kepler's laws apply to elliptical orbits, not just circular ones. Statement C is partially correct but does not specify that it applies to planets orbiting the Sun. Statement D is false as Kepler's work informed Newton's laws.
