Physics Question from JEE Main 2025 · 3 April, Shift 2

A solid steel ball of diameter $3.6 \, \text{mm}$ acquired terminal velocity $2.45 \times 10^{-2} \, \text{m/s}$ while falling under gravity through an oil of density $925 \, \text{kg m}^{-3}$. Take density of steel as $7825 \, \text{kg m}^{-3}$ and $g$ as $9.8 \, \text{m/s}^2$. The viscosity of the oil in SI unit is
