A tall cylinder is filled with viscous oil. A round pebble is dropped from the top with zero initial velocity. From the plots shown, indicate the one that represents the velocity (v) of the pebble as a function of time (t).
A
B
C
D

Explanation
Solution
When a round pebble is dropped from the top of a tall cylinder filled with viscous oil the pebble acquires terminal velocity after some time. Hence option (3) represents the correct graph.
