NEET Physics Kepler's Laws Assertion Reason Question
Assertion (A): Kepler's second law states that the line joining a planet to the Sun sweeps out equal areas in equal intervals of time. | Reason (R): This law implies that planets move faster when they are closer to the Sun and slower when they are farther from the Sun.
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.
Correct Answer
Detailed Explanation
Kepler's second law, as described, indicates that the areal velocity of a planet is constant, which results in varying speeds along its elliptical orbit. Hence, R correctly explains A.
