MCQ
From the adjacent figure, the correct observation is
  • A
    The pressure on the bottom of tank $ (a)$ is greater than at the bottom of $(b).$
  • B
    The pressure on the bottom of the tank $(a) $ is smaller than at the bottom of $(b)$
  • C
    The pressure depend on the shape of the container
  • ✓
    The pressure on the bottom of $(a) $ and $(b)$  is the same
✓

Answer

Correct option: D.
The pressure on the bottom of $(a) $ and $(b)$  is the same
d
(d)Pressure = h$\rho$g i.e. pressure at the bottom is independent of the area of the bottom of the tank. It depends on the height of water upto which the tank is filled with water. As in both the tanks, the levels of water are the same, pressure at the bottom is also the same.
