Question

A sphere of radius ‘R’ floats in a liquid of density ‘s’ such that its diameter x-x is below distance ‘h’ from free surface as shown. The density of sphere is r. The sphere is depressed slightly and released. The frequency of small oscillation is

$\sqrt{\frac{ρ R^{3}}{3 σ (R^{2} - h^{2})}}$
$\frac{1}{π} \sqrt{\frac{4 g}{3 R}}$
$\frac{1}{4 π} \sqrt{\frac{3 σ (R^{2} - h^{2}) g}{ρ R^{3}}}$
$\frac{1}{2 π} \sqrt{\frac{3 σ (R^{2} - h^{2}) g}{ρ R^{3}}}$

The correct answer is: $fraction numerator 1 over denominator 4 pi end fraction square root of fraction numerator 3 sigma left parenthesis R to the power of 2 end exponent minus h to the power of 2 end exponent right parenthesis g over denominator rho R to the power of 3 end exponent end fraction end root$

$negative pi left parenthesis R to the power of 2 end exponent minus h to the power of 2 end exponent right parenthesis times left parenthesis x right parenthesis times sigma times g equals fraction numerator 4 pi R to the power of 3 end exponent rho left parenthesis a right parenthesis over denominator 3 end fraction$
and $a equals negative omega to the power of 2 end exponent left parenthesis x right parenthesis$

A thin movable plate is separated from two fixed plates $P subscript 1$ and $P subscript 2$ by two highly viscous liquids of coefficients of viscosity $n subscript 1$ and $n subscript 2$ as shown, where $n subscript 2 end subscript equals 9 n subscript 1 end subscript.$ Area of contact of movable plate with each fluid is same. If the distance between two fixed plates is ‘h’, then the distance ‘ $h subscript 1 end subscript$ ’ of movable plate from upper plate such that movable plate can be moved with a finite velocity by applying the minimum possible force on movable plate is ( assume only linear velocity distribution in each liquid).
