A bicycle chain of length `1.6 m` and of mass `1 kg` is lying on a horizontal floor. If `g = 10 ms^(-2)`, the work done in lifting it with one end touching the floor and the other end `1.6 m` above the floor is

A uniform rod of length 4 m and mass 20 kg is lying horizontal on the ground. The work done in keeping it vertical with one of its ends touching the ground, will be -

A meter scale of mass 400 gm is lying horizontally on the floor. If it is to be held vertically with one end touching the floor, the work to be done is

A uniform rod of length 2m and mass 5kg is lying on a horizontal surface. The work done in raising one end of the rod with the other end in contact with the surface until the rod makes an angle 30^(@) with the horizontal is (g=10ms^(-2))

A thin rod of length L and mass M is held vertically with one end on the floor and is allowed to fall. Find the velocity of the other end when it hits the floor, assuming that the end on the floor does not slip?
