Hi!
If you have two identical metal feets and one of them is rubbed with Sandpaper and the other one with ordinary paper, then,
The one that was rubbed with Sandpaper, will show greater sign. This is because, the metal covering on that sheet will get scraped due to the frictional activity of the Sandpaper. Frictioncal activity of rough substances like sand paper causes the surface on which it is acting upon to wear down. On the other hand, paper has a smoother surface and will not provide enough static friction. This will cause the surface of the paper to slide over the surface of the metal sheet.
Thank You.
