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?
