Question
A square box of water has a small hole located in one of the bottom corner. When the box is full and sitting on a level surface, complete opening of the hole results in a flow of water with a speed 
, as shown in figure. When the box is still half empty, it is tilted by 45° so the hole is at the lowest point Now the water will flow out with speed of
The correct answer is:

A cylinder of square base (b × b) is kept on a rough horizontal surface so that it cannot slide but topple only. It is filled with water up to a height 2 h and a small hole of area a is punched in it at a height h. Water Leaks out horizontally from the hole. For what value of 'h', the cylinder does not get toppled?
