A plank with a uniform sphere placed on it. Rests on a smooth horizontal plane. Plank is pulled to right by a constant force `F`. It the sphere does not slip over the plank.
.

A

acceleration of centre of sphere is less than that of the plank

B

acceleration of centre if sphere is grester than tha plank because friction acts rightward on the sphere

C

acceleration of the centre of sphere may be towards left.

D

acceleration of the centre of sphere relative to plank may be greater than that of the plank relative to floor.
