268818 A bicycle chain of length\(\mathbf{1 . 6} \mathrm{m}\) and of mass \(\mathbf{1}\) \(\mathrm{kg}\) is lying on a horizontal floor. If \(\mathrm{g}=10 \mathrm{~ms}^{-2}\), the work done in lifting it with one end touching the floor and the other end \(1.6 \mathrm{~m}\) above the floor is

268819 A bucket of mass '\(m\) ' tied to a light rope is lowered at a constant acceleration of \(g / 4\). If the bucket is lowered by a distance ' \(d\) ', the work done by the rope will be (neglect the mass of the rope)

268822 Water is drawn from a well in a\(5 \mathrm{~kg}\) drum of capacity \(55 \mathrm{~L}\) by two ropes connected to the top of the drum. The linear density of each rope is \(0.5 \mathrm{kgm}^{-1}\). The work done in lifting water to the ground from the surface of water in the well \(20 \mathrm{~m}\) below is \(\left(\mathrm{g}=\mathbf{1 0} \mathrm{ms}^{-2}\right)\)
