The opening near the bottom of the vessel shown in the figure has an area A. A disc is held against the opening keep the liquid from running out. Let F1 be the net forces on the disc applied by liquid and air in this case. Now the disc is moved away from the opening a short distance. The liquid comes out and strikes the disc in elastically. Let F2 be the force exerted by the liquid in this condition. The F1/F2 is
