AIPMT MAINS 2012 Physics Circular Motion MCQ Question
Type: MCQ-conceptual-Medium-Class 11
A car of mass m is moving on a level circular track of radius R. If μₛ represents the static friction between the road and tyres of the car, the maximum speed of the car in circular motion is given by :
A
√μₛmRg
B
√Rg/μₛ
C
√mRg/μₛ
D
√μₛRg
Correct Answer
Option D
Detailed Explanation
The maximum speed is determined by the equation v = √μₛRg, derived from the balance of centripetal force and frictional force.
