Find the height of the liquid in the capillary tube if surface tension of liquid is

S

, radius of capillary tube is

r

and acceleration due to gravity is

{g}:

View answer and explanation

Correct option: A

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

Option A (

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

) is correct because it is the standard formula for capillary rise, relating surface tension, contact angle, density, radius, and gravity.

poise. A liquid rises to a height of 2 cm in a capillary tube. The angle of contact between the solid and the liquid is zero. The tube is depressed more so that the top of capillary tube is only one cm above the liquid. Then the apparent angle of contact between the solid and liquid is An object weights
