Question

Select One Correct Option from the following: A ball moves over a fixed track as shown inthe figure. From A to B the ball rolls without slipping. If surface BC is frictionless and $K_{A} ,K_{B} and K_{C}$ are kinetic energies of the ball at A, B and C respectively, then,
(A) $h_{A} \ \textgreater \ h_{C} ,K_{B} \ \textgreater \ K_{C}$
(B) $h_{A} \ \textgreater \ h_{C} ,K_{C} \ \textgreater \ K_{A}$
(C)$h_{A} =h_{C} ,K_{B} =K_{C}$
(D) $h_{A}\ \textless \ h_{C} ,K_{B} \ \textgreater \ K_{C}$.
