Assertion: On a banked curved track, vertical component of normal reaction provides the necessary centripetal force.

Question

Assertion Reasoning Type questions, 

A statement of Assertion (A) is given followed by a corresponding statement of Reason (R) just below it/of the statements, mark the correct answer as 

(A) If both assertion and reason are true and reason is the correct explanation of assertion. 

(B) If both assertion and reason are true but reason is not the correct explanation of assertion. 

(C) If assertion is true but reason is false. 

(D) If assertion is false but reason is true. 

(E) If both assertion and reason are false.

Assertion: On a banked curved track, vertical component of normal reaction provides the necessary centripetal force. 

Reason: Centripetal force is always required for turning.

Answer 1

(E) If both assertion and reason are false.

\(N \sin \theta = \frac{mv^2}R\)

Horizontal component of normal force provides the centripetal force. Hence false.

Reason:- A curved path need not always be circular path. In case of elliptical paths, the force is not necessarily centripetal.

Answer 2

Correct answer is

(E) If both assertion and reason are false.
