A road is banked with an angle 0.01 radian .If the radiaus of the road is ` 80m (g=10 m//s^(2))`then the safe velocity for the drive will be

A

`4.8 m//s`

B

`2.8 m//s`

C

`3.8 m//s`

D

`5.8m//s`

Text Solution

Verified by Experts

The correct Answer is:
B
`theta =0.1 rad,r=80 m,g=10 m//s^(2)`
`v=sqrt(rg tan theta) `
`=sqrt(80xx10xx0.01)=sqrt8=2.828 m//s`
