A 1 kg ball and 10 mg feather are released at the same time in a vacuum jar. Which one will reach the base of the vacuum jar first?

Feather Ball Neither , they will reach at the same time None will reach as there is no gravity in a vacuum

The acceleration will not depend upon the mass. So, though their weight will differ, they will reach the bottom at the same time.

there is gravity in vacuum but both will reach the bottom at the same time because they fall at the same rate regardless of their masses !

g is independent of mass. Under common note, this doesn't happen because of air resistance , and similar disturbances, in the atmosphere. In the vacuum jar, all the other forces are absent, and hence, both will reach the base at the same time. Questions are welcome.

It is not observed in day to day life due to air friction
