1.	A train is moving with a speed of 20 m/s at a place where the radius of curvature of the railway line is 1500 m. Calculate the distance between the rails if the elevation of the outer rail above the inner rail is 0.042 m ?
Answer» Solution :`l = rhg//v^(2) = 1500 XX 0.042 xx 9.8 -20^(2) = 1.54 m`
