Find the total pressure inside a sperical air bubble of radius 0.2 mm. The bubble is at a depth 5 cm below the surface of a liquid of density `2 xx 10^(3)` kg `m^(-3)` and surface tension 0.082 N `m^(-1)`. (Given : atmospheric pressure = 1.01 `xx 10^(5) Nm^(-2)`)
Hint : `P_(i) = P_(o) + (2S)/(R)`
`P_(o)` = atmospheric pressure + gauge pressure of liquid column.

Explanation

`1.028 xx 10^(5) N m^(-2)`
