Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R).

Assertion (A): Angular momentum conservation can be used to explain Kepler's second law of planetary motion.

Reason (R): Areal velocity of a planet revolving around the sun is equal to its angular momentum.

In the light of the above statements, choose the correct answer from the options given below:

View answer and explanation

Correct option: C

(A) is true but (R) is false

Option C is correct because while angular momentum conservation explains Kepler's second law, the areal velocity is proportional to angular momentum, not equal to it.
