A viscometer constructed of two 30-cm-long concentric cylinders is used to measure the viscosity of a fluid. The outer diameter of the inner cylinder is 9 cm, and the gap between the two cylinders is 0.18 cm. The inner cylinder is rotated at 250 rpm, and the torque is measured to be 1.4 N⋅m. The viscosity of the fluid is (a) 0.0084 N⋅s/m2 (b) 0.017 N⋅s/m2 (c) 0.062 N⋅s/m2 (d ) 0.0049 N⋅s/m2 (e) 0.56 N⋅s/m2
