Two objects inside an evacuated container, one with a mass three times the other

Question

Two objects inside an evacuated container, one with a mass three times the other one, are dropped from the same height. If they are dropped at the same time, which of the following is true? A. The acceleration of the lighter object is three times less than that of the heavier object. B. The lighter object is initially faster, but the heavier object will eventually catch-up with it. C. The lighter object experiences one-third the force of the heavier object. D. The heavier object will hit the ground with greater speed. E. The lighter object will hit the ground with less speed.

Explanation / Answer

Here ,

for the objects

velocity of the object after falling height h = sqrt(2 * g * h)

as this velocity is not dependent on mass of the object

the correct option is

also , the force on object = m * g

C. The lighter object experiences one-third the force of the heavier object.
