When two objects are near each other, increasing one object's mass would primarily affect the gravitational force between them. More specifically, it would increase the gravitational force that one object exerts on the other, as gravitational force is proportional to the product of the masses of the two objects, according to Newton's law of universal gravitation.
Therefore, the correct statement would be:
The gravitational force of the object would increase.
The other options are not accurate:
- The shape of the object would not change solely due to an increase in mass.
- The weight of an object depends on gravity and its mass; increasing mass would increase the weight.
- The mass of the object does not become "stronger than gravity"; rather, gravity is a force that depends on mass, so both mass and gravitational force are interconnected.
