When an object is under free fall, its acceleration depends only on the acceleration due to gravity and mass has no role to play. Due to this; irrespective of their masses, the object under free fall with have the same velocity at any instant.

Two objects of different masses falling freely near the surface of moo...
Explanation:
When two objects of different masses fall freely near the surface of the moon, they will experience the same acceleration due to gravity. This is because the acceleration due to gravity is constant on the moon's surface. Here is a detailed explanation of each option:
a) Experience forces of different magnitudes:
This statement is incorrect because both objects will experience the same force of gravity. The force of gravity acting on an object is given by the equation F = mg, where F is the force, m is the mass of the object, and g is the acceleration due to gravity. Since the acceleration due to gravity is the same for both objects, the force of gravity will be the same for both objects.
b) Have different accelerations:
This statement is incorrect because both objects will have the same acceleration. The acceleration due to gravity on the moon's surface is approximately 1.6 m/s². Therefore, both objects will experience the same acceleration due to gravity.
c) Have the same velocities at any instant:
This statement is correct. Since both objects have the same acceleration, they will have the same rate of change of velocity. This means that their velocities will be the same at any given instant during their fall.
d) Undergo a change in their inertia:
This statement is incorrect. Inertia is the tendency of an object to resist changes in its motion. It depends on the mass of an object. Since the mass of the objects remains the same, their inertia will not change. Both objects will continue to have the same inertia throughout their fall.
In conclusion, when two objects of different masses fall freely near the surface of the moon, they will have the same acceleration, the same velocities at any instant, and their inertia will remain the same. The only difference between the objects will be their weights, which depend on their masses.
