**A solid iron ball of mass 500g is dropped in mercury contained in a beaker, (a) Will the ball float or sink? Give reason. (b) What will be the apparent weight of the ball? Give reason**

Answer:

(a) The ball will float. It is because the density of the iron ball is lesser than the density of mercury.

(b) The apparent weight of the ball is zero. It is because, while floating, upthrust will be equal to the weight

"hello everyone welcome to leader
learning
i'm good great your science tutor
today's question is a solid
iron ball of mass 500 grams
is dropped in mercury
contained in a beaker a
will the ball float or sink
and give reason b
what will be the apparent weight
of the ball give reason
so in this question
a situation is given that a solid iron
ball of mass 500 gram
is dropped in the mercury contained in a
beaker so according to this situation
you have to answer the two parts
a and b let us start
for the a part they are asking will the
ball float
or sink give reason so
for the a part
that is the ball will
float
because
the density
of iron
ball is lesser
than the
density of
mercury so this is why
the ball of iron will float in the
mercury now for the b part
you have to tell what will be the
apparent weight of the ball here
since the up thrust
will be equal
to the weight
so the apparent weight here
will be
zero why it will be zero
because while floating
up thrust will be equal to the weight
weight of iron
ball here so the apparent weight will be
zero for more such videos
please subscribe leader learning and for
any doubts
drop a comment thank you"
