A spherical drop of water has radius 1 mm If surface tension of water is 70×10 -3 N/m difference of pressures between inside and outside of the spherical drop is
Text Solution
Verified by ExpertsThe correct answer is:
C
$\Delta P = \frac{2T}{R} = \frac{2 \times 70 \times 10^{-3}}{1 \times 10^{-3}} = 140 \mathrm{N/m}^2$
