A spool is placed on table top. The static friction coefficient between the table top and the spool is high.

Part (a) If the string is pulled out over the bottom of the axle as shown, in which direction will the spool roll?

MultipleChoice:

1) In the same direction as the applied force.

2) It depends on how much force is applied.

3) It will stay in one place and spin.

4) In the opposite direction of the applied force.

The best option will be 4. In the opposite direction of the applied force. If we think about angular motion and take clockwise direction as negative and anti-clockwise as positive. By finding the direction that is clockwise Or negative you can say. So, the movement of the spool will be opposite in direction of the applied force.
