The pressure inside a small air bubble of radius `0.1mm` situated just below the surface of water will be equal to `("Take surface tension of water" 70xx10^(-3)1^(J)m^(-1) "and atmospheric pressure" =1.013xx10^(5)Nm^(-2))`

A

`2.054xx10^(3)Pa`

B

`1.027xx10^(3)Pa`

C

`1.027xx10^(5)Pa`

D

`2.054xx10^(5)Pa`

Text Solution

Verified by Experts

The correct Answer is:
C
Pressure inside a bubble when it is in a liquid
`P_(o)+(2T)/(R ) = 1.013xx10^(5)+2xx(70xx10^(-3))/(0.1xx10^(-3)) = 1.027xx10^(5) Pa`.
