Detailed Solution

The iron sphere and aluminium sphere have different masses, but both spheres fall under acceleration due to gravity. i.e,

9.8 m / s^{2}

.
The term "acceleration" refers to a change in an object's velocity with respect to time.
The mass of the object has no bearing on the acceleration during free fall.
When objects are undergoing free fall conditions, and are not encountering a significant force of air resistance, they are falling under the sole influence of gravity which means acceleration due to gravity. Under such cases, the object falls under the same rate of acceleration independent of mass. The iron sphere and aluminium sphere have different masses, but both spheres fall under acceleration due to gravity. i.e,
