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 Poiseuille. Sphere Q is dropped into a liquid of density 1.6 gm ` cm ^(-3) ` and viscosity ` eta = 2` Poiseuille. The ratio of the terminal velocities of P and Q is
