Two narrow bores of diameter $\displaystyle 5.0$ mm and $\displaystyle 8.0$ mm are joined together to form a U-shaped tube open at both ends. If this U-tube contains water, what is the difference in the level of two limbs of the tube. [Take surface tension of water $\displaystyle \mathrm{T}=7.3 \times 10^{-2} \mathrm{Nm}^{-1}$, angle of contact $\displaystyle =0, \mathrm{~g}=10 \mathrm{~ms}^{-2}$ and density of water $\displaystyle =1.0 \times 10^3 \mathrm{~kg} \mathrm{~m}^{-3}$ ]
