Which of the diagrams corectly shows the change in kinetic energy of an iron sphere falling freely in a lake having sufficient depth to impart it a terminal velocity ?

A

.

B

.

C

.

D

.

Text Solution

Verified by Experts

The correct Answer is:
B
First velocity of the iron sphere increases and after sometime becomes constant, called terminal velocity. Hence, accordingly first `KE` increases and then becomes constant which is best represented by `(b)`.
