Final answer:
The object with the most gravity would be the one with the highest mass. In this case, the 500-kg mass would have the most gravity.
Step-by-step explanation:
The object with the most gravity would be the one with the highest mass. In this case, the 500-kg mass would have the most gravity.
Gravity is directly proportional to mass, so the larger the mass of an object, the greater its gravitational pull. For example, a 500-kg mass would have a greater gravitational pull than a 50-kg mass or a 5-kg mass.
Therefore, the object with a mass of 500 kg would have the most gravity.
