A ball rests upon a flat piece of paper on a table top. The paper is pulled horizontally but quickly towards right as shown. Relative to its initial position with respect to the table i.e. in the direction in which the paper is pulled. Here i.e. to the left if there is a friction between the paper and the ball. c) moves forward the ball a) remains stationary if there is no friction between the paper and the ball. b) moves to the left and starts rolling backwards the correct statement/s is /are..........
