A rod AB of mass 10 kg and length 4 m rests on a horizontal floor with end A fixed so as to rotate it in a vertical plane about the perpendicular axis passing through A. If the work done on the rod is 100 J, the height to which the end B is raised vertically above the floor is

Answer: (B)

Solution

When the rod is raised, its centre of mass (at the midpoint) rises by h/2, where
