Question

A steel ball of diameter 3.2 mm falls under gravity through an oil of density 920kg $straight m to the power of negative 3 end exponent$ and viscosity 1.64Ns $straight m to the power of negative 2 end exponent$ . The density of steel may be taken as7820kg $m to the power of negative 3 end exponent$ What is the terminal velocity of the ball?

3.45 ${cms}^{- 1}$
4.25 ${cms}^{- 1}$
1.85 ${cms}^{- 1}$
2.35 ${cms}^{- 1}$

The correct answer is: 2.35 $cms to the power of negative 1 end exponent$
