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: [Assume the radius of the tube to be negligible in comparison to l]

(a) ` P _ (atm ) A_ 0 `

(b)` (P_(atm) + rhogl ) A_0 `

(c)` (P_(atm ) + 2 rho gl) A_0 `

(d)` (P_(atm ) + 4 rho gl ) A _ 0 `

Text Solution

Verified by Experts

The correct Answer is:

Pressure exerted by fluid at closed end B is ` P = P _ (atm ) + rho g l `
` rArr ` force exerted by fluid at closed end B is ` F = PA = (P _ (atm) + rho gl ) A _ 0 `
