Consider the steady, uni-directional, fully-developed, pressure-driven laminar flow of an incompressible Newtonian fluid through a circular pipe of inner radius $5.0 \mathrm{~cm}$. The magnitude of shear stress at the inner wall of the pipe is $0.1 \mathrm{~N} \mathrm{~m}^{-2}$. At a radial distance of $1.0 \mathrm{~cm}$ from the pipe axis, the magnitude of the shear stress, in $\mathrm{N} \mathrm{m}^{-2}$, rounded off to 3 decimal places, is $\_\_\_\_\_\_\_\_$.
