Physics-Circular Motion Dynamics

NEET Physics Circular Motion Dynamics Assertion Reason Question

Type: Assertion Reason-assertion-Medium-Class 11

Assertion (A): A cyclist taking a sharp circular turn at high speed on a level road is at risk of slipping. | Reason (R): On an unbanked road, frictional force alone provides the necessary centripetal force to prevent slipping.

A

Both A and R are true, and R is the correct explanation of A.

B

Both A and R are true, but R is not the correct explanation of A.

C

A is true, but R is false.

D

A is false, but R is true.

Correct Answer

Option A

Detailed Explanation

In circular motion, especially on an unbanked road, the frictional force provides the centripetal force needed. If the speed is too high, the friction might be insufficient, risking slipping. This is supported by the NCERT context.
