Question

A body immersed in a fluid experiences an upward thrust which depends on
a) The weight of the fluid displaced by it
b) The volume of the body
c) The mass of the body
d) All of these

Answer 1

answer =b) the volume of the body.

Answer 2

$\huge\boxed{\boxed{\fcolorbox{white}{pink}{Answer}}}$

[B] The volume of the body

Some important points:

• According to the Archimedes principle the upthrust is equal to the weight of the fluid displaced.
• The weight of the fluid is directly proportional to the density of the fluid.
• It is also dependent on the relative density of the object which is emerged in the liquid with respect to the the density of the liquid.
• Also if the body has an upthrust more than that of the weight of the body then the body will float otherwise it will sink.
