The rougher the surface, the less normal force is needed.
The rougher the surface, the more normal force is needed.
Surface roughness has no impact on the normal force.
Normal force is inversely proportional to surface roughness.
Understanding the Answer
Let's break down why this is correct
Rougher surfaces have more bumps that press together. Other options are incorrect because Some think rougher surfaces mean the block is easier to hold, so less downward push is needed; Many assume roughness has no effect because only weight matters.

Definition
Friction coefficient calculations involve determining the ratio of frictional force to the normal force acting on an object. This value helps in understanding the surface interaction and the tendency of an object to move or remain stationary. Calculating friction coefficients is crucial in analyzing motion and equilibrium in Physics.
