Question:medium
The total pressure \(P\) inside an air bubble of radius \(r\) at a depth \(h\) below the surface of liquid of density \(\rho\) is (T = surface tension of liquid, \(P_0\) = atmospheric pressure)
The total pressure \(P\) inside an air bubble of radius \(r\) at a depth \(h\) below the surface of liquid of density \(\rho\) is (T = surface tension of liquid, \(P_0\) = atmospheric pressure)
Show Hint
For liquid bubble: excess pressure = \(2T/r\).
Updated On: Apr 24, 2026
- \(P_0 - h\rho g - \frac{2T}{r}\)
- \(P_0 + h\rho g + \frac{2T}{r}\)
- \(P_0 + h\rho g + \frac{4T}{r}\)
- \(h\rho g + \frac{2T}{r}\)
- \(P_0 + \frac{2T}{r}\)
Show Solution
The Correct Option is B
