"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"
