A closed vessel is half filled with water. There is a hole near the top of the vessel and air is pumped out from this hole. As a result

There are two holes P and Q at depths h and 4h from the top of a large vessel, completely filled with water. P is a square hole of side L and Q is a circular hole of radius r. If the same quantity of water flows out per second from both the holes, then the relation between L and r is

A cylindrical vessel contains a liquid up to a height h. A hole is made on the wall of the vessel. Water comes out through the hole and falls at a distance x from the base of the vessel. At what depth should the hole be created so that x becomes maximum?

A cylinderical vessel is filled with water up to height H. A hole is bored in the wall at a depth h from the free surface of water. For maximum range h is equal to

A block of wood is floating in water in a closed vessel as shown in the figure. The vessel is connected to an air pump. When more air is pushed into the vessel, the block of wood floats with (neglect compressibility of water)
