Question

A block of metal w e i g h t 5N in a air and 2N when immersed in a liquid . the buoyant forces is

Answer 1

we know,

buoyant force = weight in air - apparent weight in water.

given, weight in air = 5N

and,apparent weight = 2N

thus, buoyant force = 5-2 = 3 N

Answer 2

5N - 2N = 3N

buoyant force = 3N

as action = reaction

and according to archemedes principle
