The radius of curvature of a railway lin...

The radius of curvature of a railway line at a place when the train is moving with a speed of 36 `kmh^(-1)` is 1000 m, the distance between the two rails being 1.5 metre. Calculate the elevation of the outer rail above the inner rail so that there may be no side pressure on the rails.
