1.	An air bubble of radius r in water is at a depth h below the water surface at some instant if P is atmospheric pressure and d & T are the density and surface tension of water, what is the pressure inside the bubble ?
Answer» Solution : `"Excess of PRESSURE INSIDE the AIR BUBBLE in water" =(2T)/(r)` `:.` Total pressure inside the air bubble atmospheric pressure + pressure due to LIQUID column + Excess pressure due to surface tension `=P=hrhog+(2T)/(r)`
