Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A) : The radius vector from the Sun to a planet sweeps out equal areas in equal intervals of time and thus areal velocity of planet is constant.
Reason (R) : For a central force field the angular momentum is a constant. In the light of the above statements, choose the most appropriate answer from the options given below :
- A
Both (A) and (R) are correct and (R) is the correct explanation of (A)
- B
Both (A) and (R) are correct but (R) is not the correct explanation of (A)
- C
(A) is correct but (R) is not correct
- D
(A) is not correct but (R) is correct
