Properties of Solids and Liquids: JEE Main 2025 Physics question

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