Question

С A BI c 11. AU shape vessel shown consists of two cylindrical vertical arms A and B of cross-sectional area SA = 300 cm' and SB = 500 cm. A very light piston can slide without friction in the arm A and confines water below it. A thin light thread attached to the piston at one of its ends, passes under two ideal pulleys fixed at the bottom of the vessel and then attached at the other end to the bottom of a very light cube C of side 1 = 10 cm. Initially, when a block of mass m is placed on the piston, the cube floats with negligible portion inside the water and the thread is not slack. How high will the piston move, if the block is gradually lifted off the piston? Density of water is po = 1000 kg/m?
