An open cylindrical container with a uniform cross-sectional area \(A_1\) is filled with an ideal, incompressible fluid. A small circular drain hole of cross-sectional area \(A_2\) is located at the bottom of the container, at a vertical distance \(h\) below the top fluid surface, where \(A_2 < A_1\) but \(A_2\) is not negligible compared to \(A_1\). Both the top surface of the fluid and the exit hole are open to the atmosphere. In terms of \(g\), \(h\), \(A_1\), and \(A_2\), which of the following expressions represents the speed \(v_2\) at which fluid exits through the hole?
