$A$ sphere is rolling without slipping on a fixed horizontal plane surface. $A$ is the point of contact,$B$ is the centre of the sphere,and $C$ is the topmost point. Then:
- A$\vec{v}_C - \vec{v}_A = 2(\vec{v}_B - \vec{v}_C)$
- B$\vec{v}_C - \vec{v}_B = \vec{v}_B - \vec{v}_A$
- C$|\vec{v}_C - \vec{v}_A| = 2(\vec{v}_B - \vec{v}_C)$
- D$|\vec{v}_C - \vec{v}_A| = 4|\vec{v}_B|$
