Their velocity increases when their distance decreases from the sun in accordance with the conservation of angular momentum.

Vedclass · Answer

(A) According to Kepler's second law of planetary motion, the areal velocity of a planet revolving around the sun remains constant. This is a direct consequence of the conservation of angular momentum, as the gravitational force exerted by the sun is a central force, resulting in zero torque $(	au = 0)$.Since angular momentum $L = mvr \sin(	heta)$ is conserved, when a planet is closer to the sun (smaller $r$), its orbital velocity $v$ must increase to keep $L$ constant. Therefore, the statement in option $A$ is correct.
