Assertion: Kepler's law of areas is equivalent to the law of conservation of angular momentum.
Reason: For planetary motion

\frac{{dA}}{2 \mathrm{~m}}=\frac{{L}}{2 \mathrm{~m}}=

constant.

View answer and explanation

Correct option: A

If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion

Option A is correct because Kepler's law of areas is a direct consequence of the conservation of angular momentum, and the reason correctly relates the rate of change of area to angular momentum.
