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 F_(1) 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 F_(2) be the force exerted by the liquid in this condition. The F_(1)//F_(2) is

A. (1)/(2)
B. 1
C. (2)/(1)
D. (1)/(4)
