The opening near the bottom of the vessel has an area A.A disk is held against he opening to keep the liquid, from running out.Let F1 be the net force on the disk applied by liquid and and air in this case.Now the disk is moved away from the opening a short distance.The liquid comes out and strikes the disk inelastically.    Let F2 be the force exerted by liquid in this case.Find F1/F2.
