Question

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