Question

A car of mass m is moving on a level circular track of radius R. If μ_s represents the static friction between the road and types of the car, the maximum speed of the car in circular motion is given by

(a) √(μ_smRg) 

(b) √(Rg/μ_s)

(c) √(mRg/μ_s)

(d₎ √(μ_sRg)

Answer 1

Correct option (d₎ √(μ_sRg)

Explanation:

Force of friction provides the necessary centripetal force.
