Question

A body is immersed in a liquid. If the liquid displaced by the body weighs 1 N then what is the buoyant force acting on the body?

Answer 1

Explanation:

buoyant force =

weight of the liquid displaced

= 1 N

Answer 2

Buoyancy force = 1N

Explanation:

Buoyancy is the upward force exerted by the fluid when an object is submerged into it.

Buoyancy force = weight of object in empty space − weight of object immersed in fluid

Air's density is very small compared to the solids and liquids. Hence, the weight of an object in air is approximately the same as its weight in empty space.

As per Archimedes' principle: Any object, wholly or partially immersed in a fluid, is buoyed up by a force equal to the weight of the fluid displaced by the object.

So buoyancy = weight of displaced fluid.

As the weight of liquid displaced here is 1N, the buoyancy force on the object is equal to the same.
