Two coins of unequal mass are dropped from a balcony in vacuum. They reach the floor:
AWith different times, the heavier coin always faster
BAt the same time, since $g$ is independent of mass here
CWith the lighter coin first, due to less air drag
DOnly together if air resistance is significantly present
Answer & Solution
Correct answer: B. At the same time, since $g$ is independent of mass here
In vacuum, $g$ is independent of the body's mass; both coins fall together.
