What is meant by free fall ? Two bodies, one of mass $1\,g$ and other of mass $1\, kg$ are dropped from the same height in vacuum. Compare the two time intervals in which the two bodies will hit the ground.

Option A

Option B

Option C

Option D

Solution

Whenever objects fall towards the earth under the influence of gravitational force, it is free fall. Both will hit the ground at the same time (as acceleration due to gravity is independent of mass).
