The excess of pressure inside a soap bubble is twice the excess pressure inside a second soap bubble. The volume of the first bubble is $n$ times the volume of the second where $n$ is

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

If a section of soap bubble (of radius $R$) through its center is considered, then force on one half due to surface tension is

A capillary type tube $AB$ is connected to a manometer $M$ as shown in the figure. Stopper $S$ controls the flow of air. $AB$ is dipped into a soap solution where surface tension is $T$ . On opening the stopper for a while, a bubble is formed at $B$ end of the manometer and the level difference in manometer limbs is $h$ . If $P$ is the density of manometer soap solution and $r$ the radius of curvature of bubble, then the surface tension $T$ of the liquid is given by ...

If two soap bubbles of different radii are connected by a tube,

The pressure at the bottom of a tank containing a liquid does not depend on
