Correct answer: D. Falling stone from some height.
- A. Rain drop.
- B. Cricket ball.
- C. Falling apple from a tree.
- D. Falling stone from some height.
Explanation
The correct answer is Option D:falling stone from some height.A stone is dense and compact, which means it has a high weight-to-surface area ratio. This allows it to overcome air resistance more effectively and reach terminal velocity quickly. In contrast, objects like raindrops, cricket balls, and apples have larger surface areas relative to their mass, making them more affected by air resistance and thus slower to reach terminal velocity.

About Terminal Velocity
Terminal velocity is the constant speed reached when gravitational force is balanced by fluid resistance. The topic covers drag, buoyant force, the conditions for zero acceleration, and how viscosity, object size, shape and density affect the limiting speed, with a distinction between free fall before and after terminal velocity.
