The metro which has been recently introduced in Mumbai encounters a sharp turn between Andheri and Chakala. To avoid any derailing issues, the authorities thought of banking the rails. The turn is of a radius of 400 m and the maximum speed attained by Mumbai metro is72 km hr-1. If the distance between the rails is 1m then through what height should the outer rail be raised?
