Question 17

Consider two solid spheres P and Q each of density 8 gm cm$$^{-3}$$ and diameters 1 cm and 0.5 cm, respectively. Sphere P is dropped into a liquid of density 0.8 gm cm$$^{-3}$$ and viscosity $$\eta = 3$$ poiseulles. Sphere Q is dropped into a liquid of density 1.6 gm cm$$^{-3}$$ and viscosity $$\eta = 2$$ poiseulles. The ratio of the terminal velocities of P and Q is
