• Q2

Will it be easier for a person to push a table on a carpeted floor than on tiled floor?

Yes, because the carpeted floor is smooth, so friction is greater.

No, because the carpeted floor is rough, so friction is lesser.

Yes, because the carpeted floor is smooth, so friction is lesser.

No, because the carpeted floor is rough, so friction is greater.
