Question

define buoyancy and buoyant force . state the conditions under which a body will float or sink in a fluid/ liquid.

Answer 1

Buoyancy ÷ The ability or tendency of something to float in water or other fluid.

Buoyant force ÷ The upward force exerted by any fluid upon a body placed in it.

If the density of the body is more than the density of the liquid then it would sink whereas if the body's density is less when compared to that of the liquid it will float.

Answer 2

buoyant force:- The upward force applied on an object when it is immersed in a fluid is known as buoyant force.

Buoyancy: The property of liquid to exert an upward force on an object immersed in it is called buoyancy.

Following are the conditions under which a body will float or sink in a fluid/ liquid.

i] Volume of object : The buoyant force is greater if volume of object submerged in liquid is larger.

ii] Density of liquid : The buoyant force is greater if density of liquid is greater.
