A body of weight W is floating in a liquid. Its apparent weight will be:
(a) Equal to W
(b) Less than W
(c) Greater than W
(d) Zero
Answer:
(d) Zero
If weight W and upthrust acting on a body are equal, the body floats and hence it's apparent weight will be zero

"hello everyone welcome to lido learning
i'm good preet your science tutor
today's question is a body of weight
w is floating in a liquid
its apparent weight will be a
equal to weight b
less than weight c
greater than weight and d
zero so in this question the four
options have been given to you
and you have to tell which is best for
the
apparent weight okay we know
when the body is floating
when the body is floating
the weight w
is equals to upthrust
acting on the body
these both are equal so
the apparent weight
becomes zero
so the correct option
for this is option d
that is 0 hence
your answer is
option d zero
