What is Archimedes' principle?? The upthrust on an object in a fluid is equal to the weight of fluid displaced.
What is the force of upthrust on a boat?? The weight of water that the boat displaces.
In , why is there a resultant force upwards?? Pressure increases with depth. There is more pressure on the bottom of the object.
In , why is there pressure on the sides?? Pressure is just particles bumping into the side, so particles bump into the side too.
