Viscous forces fall into which kind of the following forces acting on a body?

Viscous forces fall into which kind of the following forces acting on a body? Correct Answer Body forces

The two types of forces acting on a fluid are body forces and surface forces. Body forces are the forces produced by the fluid element itself. Surface forces are the one acting on the fluid elements. Viscous forces act on the element and it comes under surface forces.
