Oil with a viscosity of μ= 3.8 x 10-1 N s/m2 is contained between two parallel plates. The bottom plate is fixed, while the upper plate moves when a force P is applied (see the figure below). If the distance between the two plates is b = 0.3 mm, how fast will the plates eventually move if the applied force is P = 10 N? The effective area of the moving plate is A = 1,000 cm2. How does the velocity change if we double the thickness of the oil film?
