v

_{t}= (mg)/6(pi)(eta)r

(r is the radius of the spherical body)

then, by putting the value of 'm' from m=(rho)V [where V = 4/3 * (pi)r

^{3}]

we get,

v

_{t}= 2(rho)gr

^{2}/ 9 (eta)

So in one equation, v

_{t}is directly related to r

^{2}, but in the other it is inversely related. Can someone please explain this to me.

Thak you.
