Question
Statement -1-A thin uniform rod AB of mass M and length L is hinged at one end A to the horizontal floor initially it stands vertically. It is allowed to fall freely on the floor in the vertical plane, The angular velocity of the rod when its ends B strikes the floor 
Statement -2 - The angular momentum of the rod about the hinge remains constant throughout its fall to the floor.
Statement -1 is correct (true) , Statement -2 is true and Statement- 2 is correct explanation for Statement -1
Statement -1 is true, statement -2 is true but statement- 2 is not the correct explanation four statement -1.
Statement -1 is true, statement- 2 is false
