Detailed Solution for JEE Previous Year Questions: Fluid Mechanics - Question 2

The density of ball should be greater than liquid 1 because it sinks in it.
Also density of ball should be less than density of liquid 2 as it floats on it.

A ball is made of a material of densityr where, representing the densities of oil and water, respectively. The oil and water are immiscible. If the above ball is in equilibrium in a mixture of this oil and water, which of the following pictures represents its equilibrium positions?

[AIEEE 2010]

Detailed Solution for JEE Previous Year Questions: Fluid Mechanics - Question 3

As density of ball is more than that of oil, so, it remain sunk in the oil. Therefore option A and option D are wrong as ball is floating on the oil. Now for option B, as density of water is more than that of oil, so, it remains under the oil which is in case of option B.

A uniform cylinder of length L and mass M having cross - sectional area A is suspended, with its length vertical, from a fixed point by a massless spring, such that it is half submerged in a liquid of density s at equilibrium position. The extension x0 of the spring when it is in equilibrium is : 

[JEE Main 2013]
Detailed Solution for JEE Previous Year Questions: Fluid Mechanics - Question 5


where, k is spring constant, FB is force due to buoyancy which is equal to weight of liquid displaced.
FB= σ.L.A.g /2
kx0 + σ.L.A.g /2=Mg
x0=Mg-σ.L.A.g /2/k=Mg/k(1- σ.L.A/2M)
