Question

Select One Correct Option from the following:A sphere is rolling without slipping on afixed horizontal plane surface. In the figure, Ais 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)$|\vec{V}_{C} }-\vec{V}_{A} } |=4|\vec{V}_{B} }|$
