The radius of the curved road on a national highway is `R`. The width of the road is `b`. 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 safe over it. The value of `h` is

A

`(Rg)/(bv^(2))`

B

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

C

`(v ) /(bgR)`

D

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

Text Solution

Verified by Experts

The correct Answer is:
D
`tan theta = (v^(2))/(Rg)and tan theta = (h) /(b) `

`therefore (v^(2))/(Rg) =(h) /(b ) " " therefore h= ( v^(2)b) /( Rg )`
