Question

the pressure acting опа body. which is submerged in water depends on accertation due to gravity, the density of water and the depth at which the body is located. Find the expression for pressure​

Answer 1

The pressure exerted by a fluid (such as water) on an object submerged in it depends on the depth of the object below the fluid surface, the density of the fluid, and the acceleration due to gravity.

The expression for pressure at a depth h in a fluid of density ρ is given by:

P = ρgh

where:

P is the pressure at a depth h below the fluid surface

ρ is the density of the fluid

g is the acceleration due to gravity (9.81 m/s²)

This equation is known as the hydrostatic pressure equation. It tells us that the pressure increases with depth and with the density of the fluid. The pressure is directly proportional to the depth and the density of the fluid, and it is also affected by the acceleration due to gravity.
