Given below are two statements: One is labelled as Assertion A and the other is labelled as Reason R: Assertion A: A car can move on a circular path of radius R with a speed v on a rough banked road where v is given by 0 ≤ v ≤ vmax and vmax = √[2gR((tanθ + μs)/(1 − μs tanθ))]. (symbols have usual meaning) Reason R: Static friction which is self-adjusting contributes in centripetal force when a car moves on a circular path on a rough banked road. In the light of the above statements, choose the correct answer from the options given below:
A
A is true but R is false.
B
A is false but R is true.
C
Both A and R are true and R is the correct explanation of A.
D
Both A and R are true but R is NOT the correct explanation of A.
