An iron sphere of mass $10\ kg$ has the same diameter as an aluminium sphere of mass $3.5\ kg$. Both the spheres are dropped simultaneously from a tower. When they are $10\ m$ above the ground, they have the same:
(a) acceleration
(b) momentum
(c) potential energy
(d) kinetic energy

When an iron sphere of mass $10\ kg$ has the same diameter as an aluminum sphere of mass $3.5\ kg$ are dropped simultaneously from a tower. When they are $10\ m$ above the ground, they have the same gravitational acceleration.

Therefore, option (a) is correct.
