The excess pressure inside a spherical soap bubble of radius 1 cm is balanced by a column of oil (specific gravity `=0.8`), 2 mm high, the surface tension of the bubble is

The excess pressure inside a spherical soap bubble of radius lcm is balanced by a column of oil (Sp.gr =0.8),2mm high. The surface tension of the bubble is :

The excess pressure inside a soap bubble of radius 6mm is balanced by 2mm column of oil of specific gravity 0.8. Find the surface tension of soap solution.

The excess pressure inside a soap bubble of radius 5 mm in balanced by 3 mm column of oil of specific gravity 0.6 Find the surface tension of soap solution.

If the excess pressure inside a spherical soap bubble of radius 1 cm is balanced by that due to column of oil of specific gravity 0.9, height 1.36 mm. Calculate the value of surface tension of soap solution.

If excess pressure is balanced by a column of oil (with specific gravity 0.8) 4 mm high, where R = 2.0 cm, Find the surface tension of the soap bubble.
