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

(A) When a train moves along a curved track,it follows a circular path.For a curved track,there are two rails: an inner rail and an outer rail.The center of the circular path lies on the side of the inner rail.Since the outer rail is further away from the center of the curvature than the inner rail,the radius of curvature of the outer rail $(R_{outer})$ is greater than the radius of curvature of the inner rail $(R_{inner})$.Therefore,$R_{outer} > R_{inner}$.

One end of a massless spring of spring constant $k$ and natural length $l_{0}$ is fixed,while the other end is connected to a small object of mass $m$ lying on a frictionless table. The spring remains horizontal on the table. If the object is made to rotate at an angular velocity $\omega$ about an axis passing through the fixed end,then the elongation of the spring will be
