Chapter 10, Problem 12A

Identify the action and reaction forces in the interaction between the ladybug and the whirling can in Figure 10.17.

To determine

To identify: The action and reaction forces in the interaction between the ladybug and the whirling can.

Explanation of Solution

Introduction:

Single force not exist. Force always appears in pair. To every action there is equal and opposite reaction force.

There are two forces acts on the object, while revolving in a circular motion: centripetal and centrifugal force. The centripetal force acting on the object directed towards center of a circle. The centripetal force is balance by centrifugal force which is in opposite direction. As the ladybug inside the can, centripetal force is applied on the lady bug. Ladybug feet pushes the can outward, and balance the centripetal force. As these forces are equal and opposite the ladybug remains steady at that place.

Conclusion:

Centripetal force acts on the ladybug due to which it holds tin can.
