For Newtonian fluid behaviour, the shear stress exerted by the fluid is equal to the _____.

Fluid viscosity divided by the velocity gradient parallel to the direction of shear.
Fluid viscosity divided by the velocity gradient perpendicular to the direction of shear.
Product of the fluid viscosity and the velocity gradient parallel to the direction of shear.
Product of the fluid viscosity and the velocity gradient perpendicular to the direction of shear.

Solution:

τ=µ{du}/{dx}

x is in perpendicular direction of shear stress.
