NEET 2016 Physics Banked Curves MCQ Question
Type: MCQ-numerical-Hard-Class 11
A car is negotiating a curved road of radius R. The road is banked at an angle 𝜃. The coefficient of friction between the tyres of the car and the road is μₛ. The maximum safe velocity on this road is
A
√(gR (μₛ + tan𝜃) / (¹⁻ μₛ tan𝜃))
B
√(gR (μₛ + tan𝜃) / (R² (¹⁻ μₛ tan𝜃)))
C
√(gR² (μₛ + tan𝜃) / (¹⁻ μₛ tan𝜃))
D
√(gR (μₛ + tan𝜃) / (¹⁻ μₛ tan𝜃))
Correct Answer
Option A
Detailed Explanation
The maximum safe velocity is determined by balancing the forces due to friction and banking angle, ensuring the car does not skid.
