A metal coin at the bottom of a beaker filled with a liquid of refractive index 4//3 to height of 6 cm . To an observer looking from above the surface of the liquid, coin will appear at a depth of (consider paraxial rays).

A beaker is filled with a liquid of density rho upto a height h If the beaker is at rest, the mean pressure at the walls is:

Consider a tank made of glass (refractive index 1.5) with a thick bottom. It is filled with a liquid of refractive index mu . A student finds that, irrespective of what the incident angle I (see figure) is for a beam of light entering the liquid, the light reflected from the liquid glass interface is never completely polarized. For this to happen, the minimum value of mu is :

A container of width 2a is filled with a liquid. A thin wire of weight per unit length lamda is gently placed over the liquid surface in the middle of the surface as shown in the figure. As a result, the liquid surface is depressed by a distance y ( y ltlt a ) . If the surface tension of the liquid is (4 lamda ag )/(ky) . Then value of k is .

A disc is placed on the surface of pond filled with liquid of refractive index (5)/(3) . A source of light is placed 4m below the surface of liquid. Calculate the minimum area of the disc so that light does not come out of liquid.

A rectangular tank filled with some liquid is accelerated along a horizontal surface at (40)/(3)ms^(-2) . Inside the liquid, a laser pointer is fixed a the centre of the tank which shoots a thin laser beam in the vertically upward direction. If after refraction from the liquid surface, the laser beam moves along the surface of the liquid, then what is the refrctive index of the liquid ?

A conical portion of radius R and height H is removed from the bottom of a cylinder of radius R. The volume of the remaining cylinder is V and its mass is M. It is suspended by a string in a liquid of density rho where it stays vertical . The upper surface of the cylinder is at depth h below the liquid surface . The force on the bottom of the cylinder by the liquid is

Density of a liquid varies with depth as rho=alpha h. A small ball of density rho_(0) is released from the free surface of the liquid. Then

A hemispherical portion of a radius R is removed from the bottom of a cylinder of radius R. The volume of the remaining cylinder is V and its mass is M. It is suspended by a string in a liquid of density rho where it stays vertical . The upper surface of the cylinder is at a depth of h below the liquid surface. THe force on the bottom of the cylinder by the liquid is
