A solid sphere, of radius R acquires a terminal velocity v_1 when falling (due t gravity) through a viscous fluid having a coefficient of viscosity \eta . The sphere is broken into 27 identical solid spheres. If each of these spheres acquires a terminal velocity, v_2 , when falling through the same fluid, the ratio (v_1 /v_2) equals [12 Apr 2019 Shift 2]
