Question

The pressure exerted by a liquid column of depth 0.5 m on the base of its container is 5000 Nm-2. Find the density of the liquid.​

Answer 1

We can use the formula for pressure of a liquid column:P = ρgh

where P is the pressure, ρ is the density of the liquid, g is the acceleration due to gravity, and h is the height of the liquid column.

Substituting the given values, we get:

5000 N/m² = ρ × 9.8 m/s² × 0.5 m

Solving for ρ, we get:

ρ = 5000 N/m² ÷ (9.8 m/s² × 0.5 m)

ρ = 101.02 kg/m³

Therefore, the density of the liquid is 101.02 kg/m³.
