A train is moving towards north. At one place it turns towards north-east, here we observe that
Text Solution
Verified by ExpertsThe correct answer is:
A
When a train moves from one direction to another, specifically when it turns, the geometry of the rails plays a crucial role.
In a turn, the outer rail (the rail on the outside of the turn) has to cover a longer distance than the inner rail. Hence, the radius of curvature of the outer rail is greater than that of the inner rail.
Therefore, Option A is correct because it accurately describes that the radius of curvature of the outer rail will indeed be greater than that of the inner rail during a turn.
