Vedclass · Answer

(A) $1$. If there is no friction between the paper and the ball,the paper slips under the ball. Since no horizontal force acts on the ball,it remains stationary relative to the table. Thus,statement $(A)$ is correct.$2$. If there is friction between the paper and the ball,the friction force acts on the ball in the direction of the motion of the paper (to the right). This force causes the ball to move to the right and also exerts a torque about the center of the ball,causing it to roll. Thus,the ball moves forward (to the right). Statement $(C)$ is correct,and statement $(B)$ is incorrect.
