Solution
The correct option is A acceleration
The potential energies of the spheres keep decreasing and kinetic energies increase. As they have different masses, so the potential energy is not the same. The same is applicable to the kinetic energy. The acceleration of both the spheres is the same when they are at 10 m above the ground.
