Question

Name the force acting on block when dipped in water?​

Answer 1

Answer:

the force acting apon

Explanation:

the body when it's put in water is buoyant force that is upthrust.

Answer 2

Answer:

buoyant force  

BUOYANT FORCE

➡ The upward force that is exerted on objects submerged in fluids is the buoyant force.

➡ It opposes the weight of an immersed object.

➡It is also called upthrust .

➡ The pressure at the bottom of a column of fluid is greater than at the top of the column.

Which objects float or sinks ?

➡An object whose average density is greater than that of the fluid in which it is submerged tends to sink.

➡ If the object is less dense than the liquid, the force(buoyant) can keep the object afloat.

_______________________

➡The center of buoyancy of an object is the centroid of the displaced volume of fluid.

       Archimedes' principle

➡ Archimedes' principle states that any object immersed in a fluid is acted upon by an upward, or buoyant, force equal to the weight of the fluid displaced by the object.

How to Calculate Buoyancy

Fb = Vs × D × g,

where,

Fb = buoyancy force that is acting on the object,

Vs = submerged volume of the object,

D = density of the fluid the object is submerged in,

g = force of gravity
