Embibe Experts Solutions for Exercise 6: EXERCISE 9.6

A cube of side $a$ and density $\rho$ is sliding down an incline plane with constant speed $v$. There is a thin layer of liquid between cube and surface of the plane. Coefficient of viscosity is $\eta .$ Inclined plane is at $30°$ from horizontal plane. Find thickness of liquid layer.

A lead shot of $1\mathrm{mm}$ diameter falls through a long column of glycerine. The variation of the velocity $v$ with distance covered $\left(s\right)$ is represented by

In a surface tension experiment with a capillary tube water rises upto $0.1\mathrm{m}$. If the same experiment is repeated on an artificial satellite, which is revolving around the earth, water will rise in the capillary tube upto a height of

A capillary tube (A) is dipped in water. Another identical tube (B) is dipped in a soapwater solution. Which of the following shows the relative nature of the liquid columns in the two tubes?

A long cylindrical glass vessel has a small hole of radius $r$ at its bottom. The depth to which the vessel can be lowered vertically in the deep water bath (surface tension $T$ ) without any water entering inside is

A liquid wets a solid completely. The meniscus of the liquid in a sufficiently long tube is
