1.	Water is drawn from a well in a 5 kg drum of capacity 55 L by two ropes connected to the top of the drum. The linear mass density of each rope is 0.5 kgm−1. The work done in lifting water to the ground from the surface of water in the well 20 m below is [g = 10 ms−2]
Answer» Water is drawn from a well in a 5 kg drum of capacity 55 L by two ropes connected to the top of the drum. The linear mass density of each rope is 0.5 kg $m^{- 1}$ . The work done in lifting water to the ground from the surface of water in the well 20 m below is [g = 10 m $s^{- 2}$ ]
