A small air bubble of radius 'r' is at a depth 'h' below the water surface (density of water`= rho)`. Surface tension of water is T, atmospheric pressure is `p_(0)`. Find pressure inside the air bubble for the condition `r lt lt h`

Text Solution

Verified by Experts

The correct Answer is:
B
`p-p_(h)=(2T)/(r )`
`:. p=p_(h)=(2T)/(r )`
`=p_(0)+hrhog+(2T)/(r )`.
