Hey could I please get written solution for this past paper question. The correct answers are circled

Froblem III. Two flat plates are oriented parallel to and above a fixed lower-plate, as shown im Figure III. The top thick-plate, located at a distance b above the fixed plate, is pulled along with constant speed V2. The lower thin-plate is located at a distance cb above the fixed-plate, where 0 <c <1. This plate moves with constant speed V1, which is determined by the viscous shear forces imposed upon it. Fluid 2 above the thin-plate is twice as viscous as Fluid 1 below it, which itself has a viscosity (u). 6, thick-plate V2 2 µ Fluid 2 b V1 thin-plate – Fluid 1 cb fixed-plate Figure III Question 11: What equation relates the force (F) to the cross-sectional area (A) and shear stress (T) of the top plate?
