Surface tension of a soap solution is $1.9 \times 10^{-2} \mathrm{N}/\mathrm{m}.$ . Work done in blowing a bubble of 2.0 cm diameter will be
Text Solution
Verified by ExpertsThe correct answer is:
B
$W = 8 \pi R^{2} T = 8 \pi \times (1 \times 10^{-2})^{2} \times 1.9 \times 10^{-2}$ = $15.2 \times 10^{-6} \pi J$
