Question

A Body Of Mass 20Kg and density
$8000m {}^{3}$
is completely immersed in liquid of density
$800 {m}^{3}$
Find The Up-Thrust ( Force of Buoyancy on it. ​

Answer 1

Answer:

20 N

Explanation:

The body is completely immersed so,

Volume immersed in water = volume of body = Mass/ Density = 20/8000

Buoyant force = Volume of body immersed in liquid* density of liquid* gravitational force

Therefore, Upthrust = 20/8000 * 800 * 10 = 20N

$assuming \: g = 10m /{s}^{2}$

P.S. In the question you have used the wrong unit for density. Unit of density will be kg per cubic metre. You have used the unit of volume.
