Two objects of different masses are dropped from the same height and fall freely. The acceleration due to gravity acting on them:
AIs greater for the heavier object
BDepends on the shape of each object
CIs greater for the lighter object
DIs the same for both objects
Answer & Solution
Correct answer: D. Is the same for both objects
1. From $g = \dfrac{GM}{R^2}$, $g$ depends only on Earth's mass $M$ and radius $R$.
2. It does not contain the mass of the falling object.
3. So at a given place $g$ is the same for all objects regardless of their mass.
4. Hence both fall with the same acceleration; the 'heavier object' option is the common trap.
