A cylindrical vessel filled with water upto a height

h

weighs

w

and is resting on a horizontal plane. The side of wall of the vessel has a plugged circular hole touching the bottom. The coefficient of friction between the bottom of the vessel and the plane is

\mu

. The minimum diameter of the hole so that the vessel just begins to move on the floor after the removal of the plug is:

View answer and explanation

Correct option: D

\sqrt{\frac{2 \mu w}{\pi \rho h g}}

Option D (

\sqrt{\frac{2 \mu w}{\pi \rho h g}}

) is correct because it equates the frictional force with the thrust force due to the water exiting the hole, considering the weight of the water and the height.

With the increase in temperature viscosity of a liquid - Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R
Assertion A: When you squeeze one end of a tube to get toothpaste out from the other end, Pascal's principle is observed.

Reason R: A change in the pressure applied to an enclosed incompressible fluid is transmitted undiminished to every portion of the fluid and to the walls of its container.

In the light of the above statements, choose the most appropriate answer from the options given below. Hydraulic lifts and hydraulic brakes are based
