Solution

The correct option is A
10 m

We know the Atm pressure = $10^{5} \frac{N}{m^{2}}$ [approx]
If the height of water atmosphere = h
Then, pressure due to water = $ρ$ hg
[Neglecting variation in 'g' and constant density of water]
$ρ$ hg= $10^{5}$
$1000 \times 10 \times h = 10^{5}$
H=10m(approx)

The maximum value of water pressure in the box in which water is filled upto a height of $4 m$ is equal to (atmospheric pressure $= 10^{5} N / m^{2},$ density of water $= 1000 k g / m^{3}$ , $g = 10 m / s^{2}$ )

If the atmospheric pressure is $10^{5} \frac{N}{m^{2}}$ and the density of water $10^{3} \frac{k g}{m^{3}}$ . What will be the depth below the surface of water if pressure is equal to thrice the atmospheric pressure?

Q. A water bed is

2.00 m

on a side and

30.0 c m

deep. Find the pressure that the water bed exerts on the floor. Assume that the entire lower surface of the bed makes contact with the floor.
Density of water,

ρ = 1000 k g / m^{3}; g = 10 m / s^{2}
