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 x 10 -3 Pl, the speed of block is_______x 10 -3 m/s,
