Solution

The correct option is A
$512000 P a$

The expression of pressure at the bottom of a liquid of height $h$ and density $ρ$ is given by $ρ g h$ .
The given values are:
$ρ = 1024 k g / m^{3}$ , $h = 50 m$ and $g = 10 m / s^{2}$ .
Thus, $p r e s s u r e = ρ g h = 1024 \times 50 \times 10 = 512000 P a$ .
