(1) remains stationary if there is no friction between the paper and the ball. |
(2) moves to the left and starts rolling backwards, .i.e., to the left if there is a friction between the paper and the ball. |
(3) moves forward, .i.e., in the direction in which the paper is pulled. |
A) Both (1) and (2)
B) only (3)
C) only (1)
D) only (2)
