The minimum velocity (in ms^(-1))` with which a car driver must traverse a flat curve of radius 150m and coefficient of friction 0.6 to avoid skidding is

A

`60`

B

`30`

C

`15`

D

`25`

Text Solution

Verified by Experts

The correct Answer is:
B
Using the relation
` {:(v^(2)sqrt(murg),,or,,v^(2)=murg):}`
or `v^(2) = 0.6 xx 150 xx 10`
`rArr v = 30 m//s`
