Question

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 Fig. 7(EP).15, indicate the one that represent the velocity (v) of the people as a function of time (t).
A.
B.
C. D.

Answer 1

Correct Answer - C
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.
