Vedclass · Answer

(A) When a railway track is banked (the outside rail is raised),the normal reaction force exerted by the rails on the wheels is tilted at an angle to the vertical.This normal reaction force can be resolved into two components: a vertical component that balances the weight of the train,and a horizontal component directed towards the center of the curve.This horizontal inward component provides the necessary centripetal force required for the train to move along the curved path.Therefore,the correct option is $A$.

On a railway curve,the outside rail is laid higher than the inside one so that the resultant force exerted on the wheels of the rail car by the tops of the rails will:
