The figure shows a square train wagon ABCD which has a smooth floor and side length of 2 L. The train is mov- ing with uniform acceleration (a) in a direction parallel to DA. A 'ball is rolled along the floor with a veloci- ty u, parallel to AB, with respect to the wagon. The ball passes through the centre of the wagon floor. At the instant it is at the centre, brakes are CD AB u 2 L 2 Lapplied and the train begins to retard at a uniform rate that is equal to its previous acceleration (a) (a) Will the ball hit the wall BC or wall CD or the corner C? (b) What is speed of the ball, relative to the wagon at the instant it hits a wall ?

A cylindrical glass rod of radius 0.1m and refractive index sqrt(3) lies on horizontal plane mirror. A horizontal ray of light moving perpendicular to the axis of the rod is incident on it. At what height from the mirror should the ray be incident so that it leaves the rod at a height of 0.1m above the plane mirror ? At what distance a second similar rod, parallel to the first, be placed on the mirror, such that the emergent ray from the second rod is in line with the incident ray on the first rod ?
