A solid sphere, of radius R acquires a terminal velocity v1 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 \(\left( {\frac{{{{\rm{v}}_1}}}{{{{\rm{v}}_2}}}} \right)\) equals:

1.	A solid sphere, of radius R acquires a terminal velocity v1 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 \(\left( {\frac{{{{\rm{v}}_1}}}{{{{\rm{v}}_2}}}} \right)\) equals:
A.	9
B.	1/27
C.	1/9
D.	27
Answer» B. 1/27
