Liquid of density `rho` is filled in the container of negligible mass having area A. Area of hole 'a' is very small `(alt lt A)`. Co-efficient of friction between container and surface is equal to `((a)/(A))`. As liquid is coming out of vessel, instantaneous acceleration of the container.

A

`((A)/(a)g)`

B

`(3g)/(2)`

C

`((ag)/(A))`

D

zero

Text Solution

Verified by Experts

The correct Answer is:
C
At any time
`F_("thrust")-F_("frictional")=ma`
`rhoav^(2)-mumg=ma`
`rhoa(2gh)-((a)/(A))(rhoAh)g=(rhoAh)a'`
`2rhoagh-rhoagh=rhoAha',(a)/(A)g=a'`

A container contains an incompressible and non - viscous liquid of density rho and is filled upto a height H . Now if container is moved towards right with an acceleration a then find the horizontal force exerted by liquid on the face ABCD of container . Assume container have enough height so that liquid does not fall outside the container .

A solid cube floats in a liquid of density rho with half of its volume submerged as shown. The side length of the cube is a, which is very small compared to the size of the container. Now a liquid of density (rho)/(3) (immiscible with the liquid already in the container) is poured slowly into the container. The column of the liquid of density (rho)/(3) that must be poured so that the cube is fully submerged (with its top surface coincident with the surface of the poured liquid) is :

A container is partially filled with a liquid of density rho_2 A capillary tube of radius r is vertically inserted in this liquid. Now another liquid of density rho_1(rho_1ltrho_2) is slowly poured in the container to a height h as shown. There is only denser liquid in the capillary tube. The rise of denser liquid in the capillary tube is also h . Assuming zero contact angle, the surface tension of heavier liquid is

If the pin hole in the container is very small compared to the area of the base of container and a block floats in the ideal liquid then, the speed of efflux is

A container filled with liquid up to height h is placed on a smooth horizontal surface. The container is having a small hole at the bottom. As the liquid comes out from the hole, the container moves in a backward direction with acceleration a and finally, when all the liquid is drained out, it acquires a velocity v . Neglect mass of the container. In this case
