A capillary tube is dipped into the liquid of surface tension

{S}

. The rise or fall of a liquid in a capillary tube is given as (where symbol have their usual meanings)

View answer and explanation

Correct option: C

h=\frac{2 S \cos \theta}{r \rho g}

Option C is correct. The formula for capillary rise is

h=\frac{{2 S \cos \theta}}{{r \rho g}}

.

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
