A tank of square cross section of each side l is filled ‘with.a liquid of height h. Find the thrust experienced by the vertical and bottom of the tank.

A tank having a base area of 20m^(2) and a height of 5 m is half-filled with water and the remaining half is filled with a liquid of density 0.86g*cm^(-3) . Calculate the total thrust exerted at the bottom of the tank. [ g=10m*s^(-2) ]

A hollow right circular cone of height h and of semivertical angle theta is placed with its base on a horizontal table. If the cone is filled with a liquid of density rho and the weight of the empty cone is equal to the weight of the liquid that it contains, find the thrust of the liquid on the base of the cone and the pressure exerted on the table.

The radius of a cylinderical container is r. When a liquid is poured into the container up to a height h, then the thrust on the bottom and that on the lateral surface of the container become equal. In this case

At each of the four vertices of a square of side 10 cm there is a +20 esu of charge. Find the Intensity of electric fleld at the point of Intersection of the two dlagonals.
