```							We know that -PTwo identical soap bubbles each of radius r and of the same surface tension t combine to form a new soap bubble of radius r. the two bubbles contain air temperature. if the atmospheric pressure is pnot then find the surface tension t of the soap sol in terms of po,r,r. assume process is isothermal=2T/r2*50*10^-3/1*10^-3= 100N/m²
