A beaker is filled with a liquid of density `rho` upto a height h If the beaker is at rest, the mean pressure at the walls is:

A cylinder is fill ed with a liquid of density p upto a height h. What is the hydrostatic pressure exerted by the liquid on the bottom of the cylinder, if the cylinder is kept in a lifi moving upwa rds with an acceleration a ?

The pressure inside a liquid of density rho at a depth h is :

Consider a regular tank of size (lxxb) filled with a liquid of density rho to a height H as shown in figure. Find the force at the base and on the wall of the tank.

Consider a regular tank of size (lxxb) filled with a liquid of density rho to a height H as shown in figure. Find the force at the base and on the wall of the tank.

A wooden ball of density sigma is released from the bottom of a tank which is filled with a liquid of density rho (rho>sigma) up to a height h_(1) . The ball rises in the liquid, emerges from its surface and attains a height h_(2) in air.If viscous effects are neglected,the ratio h_(2)/h_(1) is

A large vessel of height H is filled with a liquid of density rho upto the brim. A small hole of radius r is made at the side vertical face, close to the base. The horizontal force is required to stop the gushing of liquid is
