The opening near the bottom of the vessel shown in the figure has an area A disc is held against the opening to keep the liquid from running out. Let be the net force 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 inelastically. Let be the force exerted by the liquid in this condition. Then is
