Which remains the same as the distance of an object from earth changes? size of the force strength of gravity mass of the object weight of the object

B. Mass of the object

Explanation:

Only mass doesn't change whereas force, gravity, and weight will change.

Reason:

Force = Weight = Mass x Gravity

Only mass the independent factor which doesn't change anywhere in the whole world. According to newton's law of gravitation, gravity changes with change in distance from Earth's radius.

Therefore, both force and weight change with gravity.
