10Upthrust is the net upward force acting on an object in a fluid.
Upthrust decreases when the density of the liquid increases.
The SI unit of upthrust is Newton (N).
Upthrust is directly proportional to the volume of fluid displaced.
An object floats when its weight is greater than the upthrust.
Archimedes’ principle states that the upthrust on an object equals the weight of the fluid displaced.
Real weight is the weight of the object measured in a liquid.
Apparent weight is always less than the real weight for objects submerged in a liquid.
A large water-tight bottle experiences less upthrust than a smaller bottle of the same shape.
Upthrust is negligible in air compared to water.
Percentage: 0%
When an object is suspended using a spring balance in air, water and glycerin, the weights are found to be W₁, W₂ and W₃ respectively. What will be the weight of the object in those media in increasing order?
The upward force exerted by a fluid on an object is called:
Which factor affects the magnitude of upthrust?
The weight of an object measured in air is called:
A solid object floats in a liquid when:
When a stone is submerged in water, its apparent weight:
According to Archimedes’ principle, upthrust equals:
An egg floats in salty water but sinks in tap water because:
When a large and small balloon are filled with the same gas, the upthrust is:
