Question

An object is 20 cm below the surface of a liquid. The density of the liquid is 1200 kg/ m3
.
What is the pressure on the object due to the liquid?

Answer 1

Explanation:

The pressure on the object due to the liquid is 240,000 Pascal.

Given the following data:

Height = 20 meters

Density = 1200 Kg/m³

We know that acceleration due to gravity is equal to 10 m/s².

To find the pressure on the object due to the liquid, we would use the following formula;

Pressure hpg =

Where;

• h is the height of an object.

p is the density of a liquid.

g is the acceleration due to gravity.

Substituting the values into the formula, we have;Where;

h is the height of an object.

p is the density of a liquid.

g is the acceleration due to gravity.

Substituting the values into the formula, we have;

sure = 20 * 1200 * 10

Pressure = 240,000 Pa

In conclusion, the pressure on the object due to the liquid is 240,000 Pascal.

Answer 2

Ans- 2,00,000Pa

Hydrostatic pressure = ϱgh

= 1000kg/m3×10m/sec2×20m

= 2× 10^5 Pa
