Question

(a) A spherical steel ball (density p) of radius r falls under gravity through a
vertical column of a fluid (density o < p) of coefficient of viscosity n.
Will the ball attain constant velocity? If yes, under what condition ?
Can this condition be used to find value of n?
Justify giving the necessary expressions.
