A car of mass m is moving on a level circular track of radius R

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 :

Options

(a) √(µsmRg)
(b) √(Rg/µs)
(c) √(mRg/µs)
(d) √(µsRg)

Correct Answer:

√(µsRg)

Explanation:

For smoot h driving maximum speed of car v then
mv² / R = µsmg
v = √(µsRg)
