The terminal velocity of a copper ball of radius $\displaystyle 5$ mm falling through a tank of oil at room temperature is $\displaystyle 10$ cm $\displaystyle \mathrm{s}^{-1}$. If the viscosity of oil at room temperature is $\displaystyle 0.9 \mathrm{~kg} \mathrm{~m}^{-1} \mathrm{~s}^{-1}$, the viscous drag force is:
Official answer
(2)
$\displaystyle 8.48 \times 10^{-3} \mathrm{~N}$
