1. A funnel is connected to a cylindrical vessel of cross sectional area A as shown, to make an inrérconnected system of vessels. Water is poured in the cylinder such that the height of water in the funnel is 1 as shown. If the level of water in the cylindrical vessel is pushed down by a distance x <<1, the level of water in the funnel: (a) remains unchanged c) rises by x?/Ax (b) rises by Ax/xl2 (d) rises by A2x/x14 minatian are 4 15, 6, 7, 5, a and b, where a ( 0)
