A circular container of diameter is filled with water. A weightless piston is placed on the liquid surface and the water level stabilizes (also in the small tube) to a level of h. Next, a weight of 10 kg is placed on the piston causing the liquid in the small tube to rise. Calculate how high will the liquid rise in the small tube and how deep the piston will sink.
