"hello everyone welcome to leader
learning
i'm good reed your science tutor today's
question is
a boy is held inside water
contained in a vessel by tying it with
the thread to the base of the
vessel name the three forces
that keep the boy in equilibrium
and state the direction in each
force acts so
here we are going to discuss about the
forces which acts on the boy
and where what is the direction
for these forces so let us start
the forces that acts on the
boy are the first forces
up thrust up thrust
of water
on boy
this will act vertically
upward okay
next is weight of
boy weight of boy
will act vertically
downwards
and the third force which acts as the
tension in thread
tension in thread
and this will also act vertically
downwards so these are the three forces
which act on the boy and
their directions okay
these forces only help the boy to keep
in
equilibrium for more such videos
please subscribe leader learning and for
any doubts
drop a comment thank you"
