Question

A ball with a thin elastic rod moves from left to right as shown below. Which option represents the movement of the rod?

• A.

  

• B.

  

• C.

  

• D.

  

Answer 1

The Correct Option is A

This problem involves understanding the movement of a ball attached to a thin elastic rod as it moves from left to right. To solve this, we should focus on how the elastic rod behaves during and after the movement of the ball:

• Elastic Property: As the ball moves from left to right, the rod stretches and then relaxes. The elasticity allows it to extend and contract.
• Restoration: Once the ball reaches its farthest position, the rod tends to restore to its original shape or position due to its elastic nature.

Conclusion: By reviewing the options, we identify which image best represents the sequential extension and relaxation of the rod as the ball moves from left to right.

This option accurately reflects the movement: the rod first stretches as the ball moves forward and then returns to its original shape.
