What do you understand by the term upthrust of a fluid? Describe an experiment to show it's existence.

The upward force exerted on a body by the fluid in which it is submerged is called upthrust or buoyant force. Experiment If a piece of cork is placed on a surface of water in a tub, it floats with nearly of it's volume inside the water. If the cork is pushed into the water and then released, it again comes to the surface of water and floats. If the cork is kept immersed, our fingers experience some upward force. This upward force is the buoyant force.

How does the density of material of a body determine whether it will float or sink in water?

A body held completely immersed inside a liquid experiences two forces (i) F₁, the force due to gravity and (ii) F₂, the buoyant force. Draw a diagram showing the direction of these forces acting on the body and state the conditions when the body will float or sink.

Describe an experiment to show that a body immersed in a liquid appears lighter than it really is.

A body held completely immersed inside a liquid experiences two forces (i) F1, the force due to gravity and (ii) F2, the buoyant force. Draw a diagram showing the direction of these forces acting on the body and state the conditions when the body will float or sink.
