Question

A fish named Reginald became fed up with the ocean and left. Upon leaving the water, Reginald felt super heavy, it was tough to move. What he did not realize that he displaced 500 cubic centimeters of water and per Archimedes' principle he lost _________ much buoyant force on land?

In other words, how much heavier was Reginald on land than in water (use the standard metric system values for converting water volume to mass)?

Answer 1

Buoyant force is defined as

If a body weighs A newton on land and B newton on water then,

i.e., amount by which an object is heavier in another medium is given by the buoyant force

Reginald displaces of water.

Density of water

Mass equivalent of the force

Hence the fish is about 0.5 kg heavier in land than in water.
