Q1

An air bubble at a depth of 20 cm in water has a radius of 1 mm. If the inner pressure of the bubble is greater than the atmospheric pressure by \(2100\mathrm{N}/{\mathrm{m}}^{2}\), find the surface tension of the bubble.

a

\(\text{0.025 }\text{N/m}\)

b

\(0.25\text{ }\text{N/m}\)

c

\(\text{0.5 }\text{N/m}\)

d

\(\text{0.05 }\text{N/m}\)
