A road is 10 m wide. Its radius of curvature is 50 m . The outer edge is above the lower edge by a distance of 1.5 m . This road is most suited for the velocity

A

`2.5 m//s`

B

`4.5 m//s`

C

`6.5 m//s`

D

`8.5 m//s`

Text Solution

Verified by Experts

The correct Answer is:
D
`(v^(2))/(rg)=(h)/(l)`
`implies v=sqrt((rgh)/(l))=sqrt((50xx1.5xx9.8)/(10)) =8.5 7 m//s.`
