density of water = 103kg/m^3
A soap bubble, having radius of 1 mm, is blown from a detergent solution having a surface tension of 2.5 × 10^−2N/m. The pressure inside the bubble equals at a point Z0 below the free surface of water in a container. Taking g = 10 m/s^2, density of water = 103 kg/m^3, the value of Z0 is :
