Question
A large cylindrical tank of cross-sectional area 1m2 is filled with water. It has a small hole at a height of 1 m from the bottom. A movable postilion of mass 5 kg is fitted on the top of the tank such that it can side in the tank freely. A load of 45 kg is applied on the top of water by piston, as shown in figure. The value of v when piston is 7m above the bottom is (g = 10 m/s2)


Options
A.
m/s
B.10 m/s
C.1 m/s
D.11 m/s
