A train is moving towards north. At one place it turns towards north-east. Here, we observe that:

Options

  1. AThe radius of curvature of outer rail will be greater than that of the inner rail
  2. BThe radius of curvature of inner rail will be greater than that of the outer rail
  3. CThe radius of curvature of the outer and inner rails will be the same
  4. DThe radius of curvature of inner rail will be infinite

Correct answer

A. The radius of curvature of outer rail will be greater than that of the inner rail

Step-by-step solution

A centripetal force is a net force that acts on an object to keep it moving along a circular path. Any object travelling along a circular path of radius r with velocity v experiences an acceleration directed towards the centre of its path. A train is moving towards north. At one place it turns towards north-east. Here, we observe that the radius of curvature of outer rail will be greater than that of the inner rail
