Vedclass · Answer

(C) According to Kepler's second law of planetary motion,the areal velocity of a planet remains constant.This implies that the orbital velocity $v$ of a planet is inversely proportional to its distance $r$ from the sun $(v \propto 1/r)$.Therefore,the orbital velocity is minimum when the distance $r$ from the sun is maximum.Looking at the provided elliptical path,point $C$ is at the maximum distance from the sun $(S)$.Thus,the orbital velocity of the planet is minimum at point $C$.

$A$ planet is revolving around the sun in an elliptical path as shown. The orbital velocity of the planet will be minimum at:
