Q. A beaker of radius $15, cm$ is filled with a liquid of surface tension $0.75, N/m$. Force across an imaginary diameter on the surface of the liquid is

In This post you will get answer of Q.
A beaker of radius $15, cm$ is filled with a liquid of surface tension $0.75, N/m$. Force across an imaginary diameter on the surface of the liquid is

Solution:

Given that surface tension $ = 0.075 ,N/m;$

diameter $= 30 ,cm = 0.30 ,m $

$ therefore $ Force $ =0.075times 0.30$

$=0.0225,N$

$=2.25times {{10}^{-2}}N $
