Question

Which of the following examples shows an appreciable change in the shape of an object by the application of force on it?

• A. A cricket ball being hit with a bat
• B. A fan being switched on
• C. A man jumping from a certain height
• D. Repeated tearing of a paper

Answer 1

The correct option is D Repeated tearing of a paper

Only in case of repeated tearing of paper, the original shape of the paper gets distorted and it is being torn into smaller pieces.
Whereas, when a cricket ball is being hit with the bat, a change in its state of motion or direction can be observed, but a change in shape of the ball is not appreciable.
When a fan starts rotating, only its orientation changes with time repeatedly and not its shape.
Also, if a man jumps from a certain height, his body will remain in the original shape, only his state of motion will change.
