Derive an expression for terminal velocity of the sphere falling under gravity through a viscous medium.

Define terminal velocity and obtain an expression for the terminal velocity in case of a sphere falling through a viscous liquid. Also show graphically the variation of velocity with time.

The terminal velocity of a sphere moving through a viscous medium is :

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.

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 he 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:

The terminal velocity v of a small steel ball ofradius r fal ling under gravity through a column ofa viscous liquid of coefficient of viscosity eta depends on mass of the ball m, acceleration due to gravity g, coefficient of viscosity eta and radius r.
