The viscous force between two liquid layers is

Options

  1. Aradial.
  2. Bnormal to the liquid surface.
  3. Ctangential to the liquid surface.
  4. Dneither purely tangential nor purely normal.

Correct answer

C. tangential to the liquid surface.

Step-by-step solution

According to Newton's law of viscosity, = F A =- d v d z As we know that viscous force acts like friction between the layer of two fluids due to which shearing action will occur, a shear force will always act tangential to the plane of the fluid/object. So, tangential stress will be generated between the two layers of the two fluids.
