The pressure at half the depth of a lake is equal to two-third pressure at the bottom of the lake. So the depth 'h' of the lake is (\(ρ\) = density of water in the lake, \(g\) = acceleration due to gravity, \(P_0\) = atmospheric pressure).

A soap bubble of radius \( R \) is surrounded by another soap bubble of radius \( 2R \) as shown in figure. The excess pressure inside the smaller soap bubble will be (\( T \) = surface tension of soap solution)

The radii of two soap bubbles are $r_{1}$ and $r_{2}$. In isothermal condition they combine with each other to form a single bubble. The radius of resultant bubble is

The excess of pressure in a first soap bubble is three times that of other soap bubble. Then the ratio of the volume of first bubble to other is
