Question:

If the masses of two objects are almost equal then what will be the acceleration due to the force of gravitation ?

Answer:

The correct options are

A

have the same velocities at any instant.

D

The same acceleration due to the gravity of the Moon is applied to both the objects.

In a free fall, velocity depends only on the acceleration produced by gravity. The acceleration due to gravity is independent of the mass of the body. Hence, the same acceleration due to the gravity of the Moon is applied to both objects. So, they will have the same velocities at any instant irrespective of their masses. The two will not experience the same force as force is dependent on mass and the mass of the body is different here.
