Vedclass · Answer

(C) Areal velocity is defined as $\frac{dA}{dt} = \frac{L}{2m}$.Since angular momentum $L = r 	imes p = r 	imes (mv)$,we have $\frac{dA}{dt} = \frac{r 	imes mv}{2m} = \frac{1}{2}(r 	imes v)$.The direction of the areal velocity vector is the same as the direction of the angular momentum vector $L$.According to the right-hand rule for the cross product $(r 	imes v)$,the direction of $L$ is perpendicular to the plane containing the position vector $r$ and the velocity vector $v$.Therefore,the direction of the areal velocity is perpendicular to the plane of the earth's orbit around the sun.
