The viscous force between two liquid layers is (a) radial. (b) normal to the liquid surface. (c) tangential to the liquid surface. (d) neither purely tangential nor purely normal.

Answer: (c). Viscosity is internal friction between adjacent layers sliding over each other. Like friction, it acts along the surface of contact, opposing the relative motion of the layers. So the answer is (c) tangential to the liquid surface.

The viscous force between two liquid layers is

Show answer and solution

Answer: (c)

Viscosity is internal friction between adjacent layers sliding over each other.
Like friction, it acts along the surface of contact, opposing the relative motion of the layers.
So the answer is (c) tangential to the liquid surface.
