Radius of the curved road on national hi...

Radius of the curved road on national highway is r. Width of the road is l. The outer edge of the road is raised by h with respect to the inner edge so that a car with velocity v can pass safely over it. The value of h is

A

`(u^(2)b)/(Rg)`

B

`(u)/(Rgh)`

C

`(u^(2)R)/(g)`

D

`(u^(2)b)/(R)`

Text Solution

Verified by Experts

The correct Answer is:
A
`(v^(2))/(g)=(h)/(b)implies h= ("bv"^(2))/("Rg")`
