<p>An air bubble of radius 1.0 mm is observed at a depth 20 cm below the free surface of a liquid having surface tension&nbsp;<span class="equation">\(0.095 J/m^2\)</span> &nbsp; and density&nbsp;<span class="equation">\(10^3kg/m^3\)</span>&nbsp;. The difference between pressure inside the bubble and atmospheric pressure is __________<span class="equation">\(N/m^2\)</span>&nbsp;. (Take&nbsp; &nbsp;g = 10<span class="equation">\(m/s^2\)</span>​​​​​​​)</p>
