Q1

Find the pressure difference of an air bubble of radius 2 cm formed 20 cm below an open water surface and atmospheric pressure.
(Given surface tension of water = \(70\times 1{0}^{−3}\text{ }\text{N/m}\))(Shift - II Memory Based)

a

\(0.3\times 1{0}^{5}\text{ }{\text{N/m}}^{2}\)

b

\(0.02\times 1{0}^{5}\text{ }{\text{N/m}}^{2}\)

c

\(2.03\times 1{0}^{5}\text{ }{\text{N/m}}^{2}\)

d

\(1.03\times 1{0}^{5}\text{ }{\text{N/m}}^{2}\)
