An incompressible fluid (kinematic viscosity = 7.4×10−7 m^2/s, specific gravity, 0.88) is held between two parallel plates. If the top plate is moved with a velocity of 0.5 m/s while the bottom one is held stationary, the fluid attains a linear velocity profile in the gap of 0.5 mm between these plates; the shear stress in Pascal on the surface of the bottom plate is : A. 65.1 B. 0.651 C. 6.51 D. 651
