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

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
C
When a round pebbel is dropped from the top of a total cylinder filled with viscous oil the pebble acquires terminal velocity after somes time. Hence option ( c) represents the correct graph.
