A tube in vertical plane is shown in figure. It is filled with a liquid of density `rho` 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`]

Text Solution

Verified by Experts

The correct Answer is:
B
Pressure exerted by fluid at closed end `B` is
`P = rhogl`
`:.` force exerted by fluid at closed end `B` is
`F PA = lrhogA_(0)`
