A metal block of area `0.10m^(2)` is connected to a `0.010kg` mass via a string that passes over an ideal pulley (considered massless and frictionless) as in figure . A liquid with a film thickness of 0.30mm is placed between the block and the right with a constant speed of `0.085ms^(-1)` . Find the coefficient of viscosity of the liquid.
