A road is 10 m wide . Its radius of curvature is 50 m .The outer edge is above the lower edge by a 2 m .If `g=10 m//s^(2)` for what velocity of a vehicle is the road suited

A

`2.5`

B

`5m//s`

C

`25 m//s`

D

`10 m//s`

Text Solution

Verified by Experts

The correct Answer is:
D
`l=10m,r=50m ,h=2m,g=10 m//s^(2),v=?`
`v^(2)=(rgh)/(l)=(50xx10xx2)/(10)`
therefore v=10 m//s
