A `100 kg` car is moving with a maximum velocity of `9 m//s` across a circular track of radius 30 m . The maximum force of friction between the road and the car is

1000 N

706 N

270 N

200 N

Text Solution

Verified by Experts

The correct Answer is:

Maximum force of friction = centripetal force
`(mv^(2))/r = (100 xx (9)^(2))/30 = 270 N`
