A car is travelling along a curved road of radius r. If the coefficient of friction between the tyres and the road is `mu` the car will skid if its speed exceeds .
A
`sqrt((mu g)/(r ))`
B
`sqrt(mu gr)`
C
`mu rg `
D
`(mu g)/(r )`
Text Solution
Verified by Experts
The correct Answer is:
B
`F=(mv^(2))/(r )= mu mg " " therefore v= sqrt(mu g r)`
