NEET Physics Circular Motion Dynamics MCQ Question
What happens to the frictional force needed to provide centripetal force when the speed of a vehicle is less than the critical speed on a banked road?
It acts up the slope.
It becomes zero.
It acts down the slope.
It increases indefinitely.
Correct Answer
Detailed Explanation
When the speed is less than the critical speed on a banked road, the frictional force acts up the slope to provide the necessary centripetal force, as indicated in the context provided.
