no. crumbled paper has less surface than the other.so gravity on sheet will be more. so it reaches earlier.oncase ii,it may have more weight.

a) No, the crumbled paper will reach in less time because the area of crumbled paper is less than the area of sheet of paper.
Explanation:
- Formula of pressure = Thrust/Area
- In a sheet of paper the bottom area is more than the crumbled paper and so the pressure applied on sheet of paper will be less than the pressure applied on the crumbled paper.
- If you are wondering about gravity that the gravity is same on all masses and objects irrelevant of the mass.
- But if this was true than the sheet of paper and crumbled paper would fall at the same time.
- But this is only true in case of vaccum.
- On Earth there is air pressure so the sheet of paper floats .
