Vedclass · Answer

(B) The angular momentum $\vec{L}$ of a particle is defined as $\vec{L} = \vec{r} 	imes \vec{p}$,where $\vec{r}$ is the position vector and $\vec{p}$ is the linear momentum.For the magnitude of angular momentum to be zero,the cross product $\vec{r} 	imes \vec{p}$ must be zero.This occurs when the position vector $\vec{r}$ is parallel or anti-parallel to the linear momentum vector $\vec{p}$,or when either $\vec{r}$ or $\vec{p}$ is zero.Geometrically,this means the line of action of the linear momentum passes through the origin (the reference point for the position vector).
