Vedclass · Answer

(D) According to Kepler's second law of planetary motion,a line segment joining a planet and the Sun sweeps out equal areas during equal intervals of time.This implies that the areal velocity $(dA/dt)$ of the planet remains constant throughout its elliptical orbit.While the tangential,angular,and radial velocities change as the distance from the Sun varies,the areal velocity is conserved due to the conservation of angular momentum in a central force field.
