The vessel shown in the figure has two sections. The lower part is a rectangular vessel with area of cross-section A and height h. The upper part is a conical vessel of height h with base area ‘A’ and top area ‘a’ and the walls of the vessel are inclined at an angle 30° with the vertical. A liquid of density r fills both the sections upto a height 2h. Neglecting atmospheric pressure.

A spherical ball of density r and radius 0.003m is dropped into a tube containing a viscous fluid filled up to the 0 cm mark as shown in the figure. Viscosity of the fluid = 1.260 Nm–2 and its density rL= r/2 = 1260 kgm–3. Assume the ball reaches a terminal speed by the 10 cm mark. The time taken by the ball to traverse the distance between the 10 cm and 20 cm mark is (g = acceleration due to gravity = 10 ms–2)
