What is upthrust ?
When a boat is partially immersed in water, it displaces 600 kg of water. How much is the buoyant force acting on the boat in newtons ? (g = 10 m s-2)
What is meant by the term buoyancy?
Why is a force needed to keep a block of wood inside water?
It is easier to lift a heavy stone under water than in air. Explain.
Prove that the loss in weight of a body when immersed wholly or partially in a liquid is equal to the buoyant force (or upthrust) and this loss is because of the difference in pressure exerted by liquid on the upper and lower surfaces of the submerged part of body.
The base of the cylindrical vessel measures 300 cm2. Water is poured into it up to a depth of 6 cm. Calculate the pressure of water on the base in the vessel.
Select the correct option:
When an object sinks in a liquid, its:
Assertion (A): The buoyant force on a submerged rigid object can be considered to be acting at the center of mass of the object.
Reason (R): In rigid body, force distributed uniformly through its volume can be considered to be acting at the centre of mass of the body.
