There is a small hole near the bottom of an open tank filled with a liquid. The speed of the water ejected does not depend onA. area of the holeB. density of the LiquidC. height of the liquid from the holeD. acceleration due to gravity

The velocity of water exiting is given by . This does not depend on the cross-sectional area of the hole or the density of liquid. Thus, option (A) and (B) are wrong.

From the equation, the velocity depends on the height of the liquid and the acceleration due to gravity (g). So, option (C) and (D) are correct.
