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)`

Options

A.
B.
C.
D.

Answer

C

Explanation

When a round pebble is dropped from the top of a tall cylinder, filled with vissous oil the pebble acquires terminal velocity (i.e. constant velocity ) after some time. Hence option (c) is correct.
