A raindrop falling from a height h above...

A raindrop falling from a height `h` above ground, attains a near terminal velocity when it has fallen through a height `(3//4)h`. Which of the diagrams shown in figure correctly shows the change in kinetic and potential energy of the drop during its fall up to the ground ?

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
B
When drop falls first velocity increases, hence, first KE also increases. After sometime speed (velocity) is constant this is called terminal velocity, hence, KE also become constant. PE decreases continuously as the drop is falling continuously.
The variation of PE and KE is best represented by (b).
