Question

A beaker of radius 10cm is
filled
with water Calculate the force
of surface tention on any
dimetrical line on its surface.
Surface tention of water is 0.015 n/m​

Answer 1

Explanation:

L = 2 × 10 = 20 cm = 0.2 m

T = 0.075 N/m

We have,

\LARGE\sf\red{T = \frac{F}{L}}T=

L

F

∴F = TL = 0.075 × 0.2 = 0.015

=$$\large\sf\red{\fbox{\fbox{1.5 × 10^-\:^2 N}}}$$
