STANDARD Physics Circular Motion MCQ Question
Type: MCQ-numerical-Medium-Class 11
The coefficient of friction between the tyres and the road is 0.1. The maximum speed with which a cyclist can take a circular turn of radius 3 m without skidding is (Take g = 10 m s⁻²)
A
√15 m s⁻¹
B
√3 m s⁻¹
C
√30 m s⁻¹
D
√10 m s⁻¹
Correct Answer
Option B
Detailed Explanation
The maximum speed without skidding is given by v = √(μrg). Substituting the values, v = √(0.1 × 3 m × 10 m s⁻²) = √3 m s⁻¹.
