Assertion: If gravitational force is proportional to

\frac{1}{\mathrm{R}^3}

then Keplar's second law would not be affected.
Reason: For Keplar's second law, central nature of force is the only condition.

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 second law depends only on the central nature of the force, not the specific radial dependence.
