let's understand
why objects weigh lighter in water
according to the Archimedes's principle
let us suppose the weight of the stone
in air
is w1 when the same stone is immersed
in water its weight is different
specifically its weight reduces
so let us try to understand
why the weight of the stone is different
in water
when the stone is dipped into the water
it displaces water of its equal volume
and the weight of the displaced water
is equal to the apparent weight loss
of the stone and this my dear friend
is called the Archimedes' principle
let us now now try to understand the
reason
behind this principle
[Music]
so weight of the stone is acting
downward
if the same stone is
dipped into the water the weight of the
stone
is acting downward
while the upthrust provided by the
displaced water is acting in
upward direction
the balance of these forces
results in stone weighing
lesser in water, i hope you understand.
there are few things to keep in mind
that the volume of displaced water
equals to volume of the stone
and the weight of the displaced water
is equals to the apparent weight loss in
a stone
is also known as the up thrust
