A motor cyclist riding at `36kmh^(-1)` has turn a corner. Find the least radius of the curve, he should follow for safe travelling, if the coefficient of friction between the tyres and the road is `0.2`.

A

10 m

B

25 m

C

50 m

D

100 m

Text Solution

Verified by Experts

The correct Answer is:
C
For safe circular turn
`v=sqrt(murg)`
`rArr" "r=(r^(2))/(mug)rArrr=((10)^(2))/(0.2xx10)=50m`
