Water is poured to the same level in each of the vessels shown, all having the same base area (Fig. 15-17). If the pressure is the same at the bottom of each vessel, the force experienced by the base of each vessel is the same. Why then do the three vessels have different weights when put on a scale? This apparently contradictory result is commonly known as the hydrostatic paradox.

This shows that the weight of the object depend son it volume.
In the given three vessels, the shapes of the vessels are different. Even though the water in the vessels is at the same level, the amount of water is not the same in all the three vessels. This shows that the volume of the water contained in all the three vessels are not the same. Thus, the weight of the water exerted by the three vessels will not be the same.
Therefore, the three vessels have different weights when put on a scale.

Three identical balls are placed on a frictionless horizontal surface touching each other. They stick to each other because of adhesive. Another ball of same radius and mass m is placed over the void created by the three balls. Find the forces applied by the balls kept on the floor to each other if the system remains in equilibrium.

An object of mass m = 0.25 kg oscillates in a fluid at the end of a vertical spring of spring
constant kH = 85 N/m, see Fig.1. The effect of the fluid resistance is governed by the
damping constant b = 0.07kg/s.
(i) Find the period of the damped oscillation.
(ii) By what percentage does the amplitude of the oscillation decrease in each cycle?
