Figure shows a container of width H. A telescope is fitted at a height H above the base on its side wall such that it is focussed at the point A as shown. Now a liquid is poured slowly in the container. The refractive index of liquid is `mu = sqrt(2)`. Select the correct alternatives

A

When level of liquid column is h, the point of focus is at a distance `h(1-(1)/(sqrt(3)))` from A

B

When level of liquid is h, the point of focus is at `(h)/(sqrt(3))` from A

C

When level of liquid exceeds H, point of focus is always at `(H)/(2)` from A

D

When level of liquid exceeds H, point of focus is A

Figure shows two -containers P-and Q with same base area A and each filled upto same height with same liauid. Select the correct alternative

Prove that the average pressure of a liquid (density p) on the walls of the container filled upto height h with liquid is 1/2 h rhog .

Consider the situation shown in figure. A plane mirror is fixed at a height h above the bottom of a beaker containing water (refractive index mu ) up of a bottom formed by the mirror.

A solid cube floats in a liquid of density rho with half of its volume submerged as shown. The side length of the cube is a, which is very small compared to the size of the container. Now a liquid of density (rho)/(3) (immiscible with the liquid already in the container) is poured slowly into the container. The column of the liquid of density (rho)/(3) that must be poured so that the cube is fully submerged (with its top surface coincident with the surface of the poured liquid) is :

A container shown in figure contains a liquid to depth H, and of density rho The gauge pressure at point P is :

Equal volumes of a liquid are poured in the three vessels A, B and C (h_(1) lt h_(2) lt h_(3)) . All the vessels have the same base area. Select the correct alternatives.

Consider a tin can of height h as shown in the figure. A coin lies on the botttom at the centre. From the position shown you can barely see the far side of the bottom of the can. When the can is slowly filled with water of refractive index mu , coin is just visible when the can is full. Show that the ratio of the height to radius is h/r=2sqrt((mu^2-1)/(4-mu^2))
