Question

The viscous force acting between two layers of a liquid is given by $\frac{F}{A} = - η \frac{d v}{d z}$ . This F/A may be called
(a) pressure
(b) longitudinal stress
(c) tangential stress
(d) volume stress

Open in App

Solution

Correct option: (c)
The viscous force acts tangentially between two parallel layers of a liquid. In terms of force on a material, it is analogous to a shearing force.
