Buoyant force experienced by a solid is _____ the weight of the fluid displaced by it

Submarine's lactometers, hydrometers, etc. are designed according to __________.

Assertion: To float; a body must displace liquid whose weight is equal to the actual weight.
Reason: The body will experience no net downward force in that case.

State whether the following statements are true or false:
(a) The buoyant force depends on the nature of object immersed in the liquid
(b) 'Archimedes' principle can also be applied to gases.

Buoyant force exerted by a fluid on a given body is :

Is the buoyant force on a submerged object equal to the weight of the object itself or equal to the weight of the fluid displaced by the object?

State Archimedes principle. Explain the law of floatation of bodies in a liquid.
