According to the law of gravitation, the gravitational force acting between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. In a vacuum, both balls experience the same gravitational force from Earth since they are dropped from the same height. As the size or shape of the object does not affect the acceleration due to gravity, both balls will accelerate at the same rate towards the Earth, irrespective of their masses. Therefore, the best choice is A) The balls accelerate at the same rate.
