Pascal's law states that The pressure at any point in the fluid is equal in all directions.

Recall high-pressure exertion in a small surface area

Recall pressure and thrust.

The buoyant force depends on the body's volume, density of the liquid, and acceleration due to gravity.

Fluids exert the same pressure in all directions at the same level. The example satisfies the statement

Calculate the pressure first by the getting product of (h x rho x g).Then calculate thrust =pressure x area

Buoyancy or upthrust refers to an upward force exerted by a fluid that opposes the weight of a partially or fully immersed object

Iron nail has lesser density than that of mercury

The pressure at a point in a liquid depends upon acceleration due to the gravity (g), the density of the liquid (p), and the point below the free surface (h).

A dam has broader walls at the bottom than at the top. As, the depth increase, the pressure applied by water on the walls of the dam also increases.
