A circular cylinder of mass m, diameter D and length L is pulled vertically upwards within a cylinder of diameter of D + 2t by a force of magnitude P. If the mass moves with a constant velocity, U, and the cylinders are separated by a fluid with viscosity , what is the value of P? Is it: P= #DLUμ tmg P = #DLUμ t P= P = mg P= #DLUμ t DLUμ t - mg + mg
