A thread is tied slightly loose to a wire frame as shown in the figure And the frame is dipped into a soap solution and taken out The frame is completely covered with the film. When the portion A is punctured with a pin the thread

The fundemantal quantity which has the same power in the dimensional formula of surface tension and coefficient of viscosity is:                    

A thin wire ring of $3cm$ radius float on the surface of a liquid. The pull required to raise the ring before the film breaks is $30.14\times 10^{-3}N$ more than its weight. The surface tension of the liquid (in $N{m}^{-1}$) is:

A disc of paper of radius $R$ has a hole of radius $r$. It is floating on the surface of a liquid of surface tension ${}^{\prime }{T}^{\prime }$. Then force of surface tension on the disc is:

Is surface tension a vector?

When a 'U' shaped slider of negligible mass is dipped in a soap solution and lifted, a thin film of soap is formed in the frame. It supports a weight of 2.0 x 10${}^{-2}$ N. If the length of the slider is 40cm, the surface tension of the film of soap is:

A certain number of spherical drops of a liquid of radius r coalesce to form a single drop of radius R and volume V. If T is the surface tension of the liquid, then

The surface tension of water is $7\times 10^{-2}N/m.$ The weight of water supported by surface tension in a capillary tube of 0.1 mm radius, will be __________.

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

A drop of mercury of radius $2mm$ is split into $8$ identical drops. Find the increase in surface energy. Surface tension of mercury $=0.465J{m}^{-2}$
