Solid friction, like viscosity is
...Solid friction, like viscosity is
independent of the surface area in contact
independent of the relative motion between layers
dependent on normal reaction
in opposition to motion
Correct answer is D
The force acting on a body due to the viscous resistance of the surrounding fluid is called the drag force and it acts in the direction opposite to the direction of motion. So also does friction.
