While determining the coefficient of viscosity of the given liquid, a spherical steel ball sinks by a distance {\h}=0.9 {\m}. The radius of the ball {\r}=\sqrt{3} \times 10^{-3} {\m}. The time taken by the ball to sink in three trails are tabulated as follows. Trial No. Time taken by the ball to fall by h (in second) 1. 2.75 2. 2.65 3. 2.70 The difference between the densities of the steel ball and the liquid is 7000 {\kg} {\m}^{-3}. If {\g}=10 {\ms}^{-2}, then the coefficient of viscosity of the given liquid at room temperature is

0.14 \times 10^{-3} {\Pa} . { s}
