NEET Physics (general) Assertion Reason Question
Type: Assertion Reason-assertion-Hard-Class 11
Assertion (A): The maximum possible speed of a car on a banked road with friction is greater than that on a flat road. | Reason (R): For the maximum speed on a banked road, the frictional force provides the necessary centripetal force.
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 B
Detailed Explanation
The assertion is true as per the derivation in Eq. (4.21) where it shows v_max on a banked road is greater. However, the reason is incorrect because it's the combination of the normal force and friction that provides the necessary centripetal force, not friction alone.
