Question
A tube in vertical plane is shown in figure. It is filled with a liquid of density r and its end B is closed. Then the force exerted by the fluid on the tube at end B will be : [Neglect atmospheric pressure and assume the radius of the tube to be negligible in comparison to l]
Options
A.0
B.ρ g l A0
C.2ρ g l A0
D.Cannot be determined
Solution
Pressure exerted by fluid at closed end B is
P = ρgl
∴ force exerted by fluid at closed end B is
F = PA = lρg A0
P = ρgl
∴ force exerted by fluid at closed end B is
F = PA = lρg A0
