A metal block of base area $0.20\,m ^2$ is placed on a table, as shown in figure. A liquid film of thickness $0.25\,mm$ is inserted between the block and the table. The block is pushed by a horizontal force of $0.1\,N$ and moves with a constant speed. If the viscosity of the liquid is $5.0 \times 10^{-3} \;Pa-s$, the speed of block is $.........\times 10^{-3}\,m / s$
