A soap bubble, having radius of mm, is blown from a detergent solution having a surface tension of N/m. The pressure inside the bubble equals at a point below the free surface of water in a container. Taking m/s density of water kg/m the value of is:
cm
cm
cm
cm
To solve this problem, we need to find the pressure inside the soap bubble and equate it to the pressure at a depth below the water surface.The excess pressure inside a soap bubble is given by:
