A railway track is banked for a speed v, by making the height of the outer rail h higher than that of the inner rail. The distance between the rails is d. The radius of the curvature of the track is r

A

`(h)/(d)=(v^(2))/(rg)`

B

`tan(sin^(-)(h)/(d))=(v^(2))/(rt)`

C

`tan^(-1)((h)/(d))=((v^(2))/(rg))`

D

`(h)/(r)=(v^(2))/(dg)`
