When the bulb is squeezed then liquid level rises to height h i.e. pressure decreases inside the bulb which causes rises in the tube
for common elevation i.e. at liquid level pressure must be equal therefore
for
for
Horizontal speed of the ball is given as
height of the ball is given as
now the time taken by the ball to reach the bottom is given as
now we will plug in all values
now the distance from the base is given as
`
so it will land at distance of 40.4 m
