Terminal Velocity

A spherical ball is dropped in a long column of a highly viscous liquid. The curve in the graph shown, which represents the speed of the ball (v) as a function of time (t) is

Show answer and solution

Answer: (b)

The ball starts from rest, so $v = 0$ at $t = 0$ (rules out C and D).
Viscous drag increases with speed, so acceleration decreases and $v$ cannot rise linearly (rules out A).
$v$ rises and then becomes constant at terminal velocity: curve B.
So the answer is (b) B.
