Vedclass · Answer

(A) The angular momentum $\vec{L}$ of a particle is defined as the cross product of its position vector $\vec{r}$ and its linear momentum $\vec{p}$,given by $\vec{L} = \vec{r} 	imes \vec{p}$.By the definition of the cross product,the resulting vector $\vec{L}$ is always perpendicular to the plane containing the vectors $\vec{r}$ and $\vec{p}$.Since the particle moves in a plane of rotation,both $\vec{r}$ and $\vec{p}$ lie within this plane.Therefore,the angular momentum vector $\vec{L}$ is always perpendicular to the plane of rotation.
