STANDARD Physics Motion in Fluids MCQ Question
Type: MCQ-conceptual-Medium
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
v-t graph with constant slope
B
v-t graph with increasing slope
C
v-t graph with decreasing slope
D
v-t graph with constant velocity
Correct Answer
Option C
Detailed Explanation
As the pebble falls through the viscous oil, it reaches terminal velocity, resulting in a v-t graph with a decreasing slope.
