a U- tube limb of radius 0.5 cm and the other limb of radius 0.1 cm .water is poured into the tube .find the difference in level of water in the two tubes .S.T of water =0.070 N/m

Dear Student ,
here in this question the given data is , density of water = $\rho$ = 1000 kg/m³ ,
radius of limbs , $r_1=0·1 cm =1\times {10}^{-3} m and r_2=0·5 cm =5\times {10}^{-3} m$ ,
surface tension , T = $0·07 N/m$
Now difference in level of water in two tubes ,
$$\begin{gathered} h_1-h_2=\frac{2T}{\rho g}\left(\frac{1}{r_1}-\frac{1}{r_2}\right)=\frac{2\times 0·07}{1000\times 9·8}\left(\frac{1}{1\times {10}^{-3}}-\frac{1}{5\times {10}^{-3}}\right) \\ =0·01 m \end{gathered}$$
