In the arrangement as shown, A and B arc two cylinders each of length L and density d1 and d2(d1<d2) respectively. They are joined together and submerged in the liquid of density d with length L/2 of A outside the liquid. If the difference in densities of two cylinders is equal to density of the liquid, find d1.

A large open tank has two holes in the wall. One is a square hole of side L at a depth y from the top and the other is a circular hole of radius R at a depth 4y from the top. When the tank is completely filled with water, the quantities of water flowing out per second from both holes are the same. Then, R is equal to

A hollow cylindrical container floats in water with half its length immersed. A liquid of specific gravity σ is slowly poured into the container until the levels of the liquid inside the container and of water outside are the same. It is observed that the container is submerged to two-thirds its length. Then the value of σ is
