An ideal liquid of density `rho` is filled in a horizontally fixed syringe fitted with a piston. There is no friction between the piston and the inner surface of the syringe. Cross-sectional area of the syringe is A. At one end of the syringe, an orifice is made. When the piston is pushed into the syringe, the liquid comes out of the orifice and then following a parabolic path falls on the ground.
With what velocity does the liquid come out of the orifice?

Options

A. `sqrt((F)/(rhoA))`
B. `sqrt((2F)/(rhoA))`
C. `sqrt((F+2rhoghA)/(rhoA))`
D. `sqrt((F+rhoghA)/(rhoA))`

Answer

B

Explanation

Bernoullis principle.
