A solid sphere, of radius `R` acquires a terminal velocity `v_(1)` when falling (due to 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 :
A solid sphere, of radius R acquires a terminal velocity v_(1) when falling (due to gravity) through a viscous fluid having a coefficient of viscosity h. 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)) equal 9/x . Find the value of x.
