A thin equiconvex glass lens (mu_(g)=1.5) is beign placed on the top of a vessel of height h=20cm as shown figure. A luminous point source is beign placed at the bottom of vessel on the principal axis of the lens. When the air is on both the side of the lens the image of luminous source is formed at a distance of 20cm from the lens out side the vessel. When the air inside the vessel is being replaced by a liquid of refractive index mu_(l) the image of the same source is being formed at a distance 30cm from the lens outside the vessel. Find the mu_(l) .

Consider the situation shown in figure. Water (mu_(w) = (4)/(3)) is filled in a breaker upto a height of 10 cm. A plane mirror is fixed at a height of 5 cm from the surface of water. Distance of image from the mirror after reflection from it if an object O at the bottom of the beaker is

Water is filled to height h in a fixed vertical cylinder placed on horizontal surface. At time t = 0 a small hole a drilled at a height h//4 from bottom of cylinder as shown. The cross section area of hole is a and the cross-section area of cylinder is A such that A gtgt a . Let the value of horizontal distance of point where the4 water fall on horizontal surface from bottom of cylinder be x as shown. Then from time t = 0 till water comes out of hole, pick the correct statement:

There is a hole at the bottom of a large open vessel. If water is filled upto a height h, it flows out in time t. if water is filled to a height 4h, it will flow out in time

Water level is maintained ina cylindrical vessel up to a fixed height H. The vessel is kept on a horizontal plane. At what height above the bottom should a hole be made in the vessel so that the water stream coming out of the hole strikes the horizontal plane at the greatest distance from the vessel.

A point source of light S is placed at the bottom of a vessel containg a liquid of refractive index 5//3. A person is viewing the source from above the surface. There is an opaque disc of radius 1 cm floating on the surface. The centre of the disc lies vertically above the source S. The liquid from the vessel is gradually drained out through a tap. What is the maximum height of the liquid for which the source cannot at all be seen from above?
