A soap bubble, having radius of 1 mm,is blown from a detergent solution having a surface tension of $$2.5 \times 10^{-2}N/m.$$ The pressure inside the bubble equals at a point $$Z_0$$, below the free surface of water Taking $$g = 10 m/s^2$$, density of water $$= 10^3 kg/m^3$$, the value of $$Z_0$$ is :

A
