When does an object float or sink when placed on the surface of a liquid ?
Which of the following will sink or float on water? (Density of water = 1 g Cm-3)
body D having density 0.85 g m-3
(i) The diameter of neck and bottom of a bottle are 2 cm and 10 cm, respectively. The bottle is completely filled with oil. If the cork in the neck is pressed in with a force of 1.2 kgf, what force is exerted on the bottom of the bottle?
(ii) Name the law/principle you have used to find the force in part (a).
How is the upthrust related to the volume of the body submerged in a liquid?
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.
A balloon filled with helium gas floats in a big closed jar which is connected to an evacuating pump. What will be your observation, if air from the jar is pumped out? Explain your answer.
Select the correct option:
When a body is wholly or partially immersed in a liquid, it experiences a buoyant force which is equal to:
Is thrust a scalar or vector quantity?
How is thrust different from pressure?
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.
