Question
An air bubble is lying just below the surface of water. The surface tension of water is 70 × 10-3 Nm-1 and atmospheric pressure is 1.013 × 105 Nm-2. If the radius of bubble is 1 mm, then the pressure inside the bubble will be : -
Options
A.1.0270 × 105 Pa
B.1.0160 × 105 Pa
C.1.0144 × 105 Pa
D.1.0131 × 105 Pa
Solution
Pin = Patm + 
= 1.013 × 105 +
= 1.0144 × 105 Pa
= 1.013 × 105 +
= 1.0144 × 105 PaCreate a free account to view solution
