Solving time: 3 mins

A thin wire ring of $3 c m$ radius float on the surface of a liquid. The pull required to raise the ring before the film breaks is $30.14 \times 1 0^{- 3} N$ more than its weight. The surface tension of the liquid (in $N m^{- 1}$ ) is:

80 \times 1 0^{- 3}

87 \times 1 0^{- 3}

90 \times 1 0^{- 3}

98 \times 1 0^{- 3}

Extra pull to overcame surface tension is

30.14 \times 1 0^{3} N

⟹ 30.14 \times 1 0^{- 3} = 2 \times 2 π \times (0.03) \times T

⟹ 79.9 \times 1 0^{- 3} N / m = T
