A metal plate of area `0.10 m^(2)` is connected to a `0.04 kg` mass via a string that passes over an ideal pulley (considered massless and frictionless) A liquid with a film of thickness of `0.3mm` is placed between the plate and the table. When system is released, the plate moves up with constant speed of `0.085 m//s`. Find the approximate value of coefficient of viscosity of the liquid. (mass of metal plate is `0.02 kg`, `g=9.8 m//s^(2)`)
