Question
A layer of oil 1.50 mm thick is placed between two microscope slides. Researchers find that a force of $5.50 \times 10^{-4} \textrm{ N}$ is required to glide one over the other at a speed of 1.00 cm/s when their contact area is $6.00 \textrm{ cm}^2$. What is the oil's viscosity? What type of oil might it be?

$0.138 \textrm{ Pa}\cdot\textrm{s}$
