For a sliding plate viscometer of the type we have discussed in class, it is found that when the bottom plate has dimensions

of $50cm50cm,$ the distance between the plates is $1mm,$ the viscosity of the Newtonian fluid is $670$mPa.$s$ and the upper

plate is pulled at a velocity of $0\mathrm{.}5\frac{m}{s},$ the shear stress that develops at the upper plate is

Select one:

a$.335$kPa;

cross out

b$.335Pa$;

cross out

C$.83\mathrm{.}8Pa$;

cross out

d$.83\mathrm{.}8N$;

cross out

e$.$ None of the above;
