Question

When a person walks on a horizontal rough surface, then mark the incorrect statement about friction between his shoes & the surface.

• A. friction causes the motion
• B. friction is opposite to tendency of slipping
• C. friction is kinetic
• D. friction is less than or equal to ${\mu }_{s}N$

Answer 1

The correct option is C friction is kinetic



F acts opposite to the tendency of slipping and hence the person can walk without slipping. Since person does not slide friction is maximum and static.
