A metal block of area `0.10 m^2` is connected to a 0.010 kg mass via a string that passes over an ideal pulley (considered massless and frictionless) as in fig.A liquid with a film thickness of 0.30 mm is placed between the block and the table.When released,the block moves ot the right with a constant speed of `00.085 m s^(-1)`.Find the coefficient of viscosity of the liquid.
