A solid sphere of radius Racquires a terminal velocity when falling (due to gravity) through a viscous fluid having a coefficient of viscosity η. The sphere is broken into 27 identical solid spheres. If each of these spheres acquires a terminal velocity v₂ when falling through the same fluid, the ratio (v1/v2) equals - VgyanHub
