Question
A steel ball of diameter 0.2mm, falls with a
terminal velocity of 0.0029m/s through oil in a
relatively large jar.Calculate the viscosity of
oil, assuming the densities of the oil and the
ball are to be 7200 and 420kg/m^3 respectively
.if the radius is doubled,calculate the new
terminal velocity.[take g=9.8m/s^2]
