Upthrust in hindi

Definition of upthrust“When an object is immersed in a liquid, an upward force is exerted on that object by the liquid, which is called the buoyancy force or buoyancy of that liquid.”

Center of Buoyancy –Buoyancy is equal to the weight of the fluid displaced by the object and acts upwards through the center of gravity of the removed fluid, that point is called the center of buoyancy of the fluid.

in formula,

{\displaystyle f_{\mathrm {buoyancy} }=-\rho vg\,}Where V is the volume of the object that is immersed in, or inside the liquid. p = density of the liquid and g = acceleration due to gravity

• Due to the buoyancy of the fluid, there appears to be a decrease in the weight of an object immersed in water.

Explanation of Upthrust

When we dip a piece of wood under water, we have to exert a downward force on it. When we remove this force by taking it to some depth under water, then the piece automatically comes up and floats on the surface of the water.

From this it appears that when an object is immersed in a liquid, an upward force acts on it. Similarly, while drawing water from a well, we experience

That as long as the bucket remains submerged in the water of the well, it appears light and as soon as the air comes out of the water, it appears heavy. From this it appears that when an object is immersed in a liquid, an upward force acts on it,

Due to which the object feels somewhat lighter than its actual weight. This property of a liquid due to which it exerts an upward force on objects is called buoyant or buoyant force.

Now the question arises that when a piece of wood is left immersed in water, it floats on the surface, but why does an iron nail sink in water? The reason for this is that when an object is immersed in a liquid, its weight, that is, the gravitational force, acts downward and the buoyant force acts upward. The direction in which the resultant of these two forces acts,

The object moves in the same direction. If the resultant of both the forces acts upwards in the fluid then the object will move up and if the resultant acts downwards the object will sink down. In a piece of wood it acts upwards and in an iron nail it acts downwards.
