A metal block of base are `0.20m^(2)` is placed on a table,as shown in figure.A liquid film of thickness `0.25mm` is inserted between the block and the table.The block is pushed by a horizontal force of `0.1N` and moves with a constant speed.If the viscosity of the liquid is `5.0times10^(-3)Pt`,the speed of block is `times10^(-3)m/s`

A metal block of area 0.10 m^(2) is connected to a 0.01 kg mass via a string that passes over a massless and frictionless pulley as shoen in figure.A liquid with a film thickness of 0.3 mm is placed between the block and the table.

A metal block of area 0.10 m^(2) placed at a table, is connected to a 0.010 kg mass via a string that passes over an ideal pulley. Th pulley is fixed at the edge of the table. A liquid with a film of thickness 0.30 mm is placed between the block and the table.

A block of mass 10 kg is placed on a horizontal surface as shown in the figure and a force F = 100 N is applied on the block as shown, in the figure. The block is at rest with respect to ground. If the contact force between block and ground is 25n (in Newton) then value of n is : (Take g = 10 m//s^(2))

A cubical block ofmass sqrt(3)/(10) kg and edge 20cm is placed on a rough horizontal surface as shown in the figure-5.126. A force of 1N is applied at one end of the block and the block remains stationary. The normal force exerted by the surface on the block acts (g= 10 m//s^(2))
