A tank filled with water to a height of \(1.5\,\text{m}\) contains a cube of side \(10\,\text{cm}\) and density \(1.5\,\text{g cm}^{-3}\) resting at the bottom. The tank is placed in a lift moving downward with an acceleration \(2\,\text{m s}^{-2}\). The work required to pull the cube vertically upward through a distance of \(1\,\text{m}\) is \[ (g=10\,\text{m s}^{-2}) \]
