Determine excess of pressure in side air bubble

Determine excess of pressure in side soap solution bubble.

Determine excess of pressure in side liquid drop

What is the excess pressure inside a bubble of soap solution of radius 5.00 mm,given that the surface tension of soap solution at the temperature (20^@C) is 2.50xx 10 2 N in 1 ? If an air bubble of the same dimension were formed at depth of 40.0 cm inside a container containing the soap solution (of relative density 1.20), what would be the pressure inside the bubble ? (1 atmospheric pressure is 1.01xx 105 Pa).

Surface tension of water is 0.072 Nm^-1 . The excess pressure inside a water drop of diameter 1.2 mm is
