Step 1
Which property affects the gravitational field strength of an object?
Answer
The gravitational field strength of an object is primarily affected by its mass. According to Newton's law of universal gravitation, the force of attraction between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
The formula can be expressed as:
where:
- is the gravitational force between the objects,
- is the gravitational constant,
- and are the masses of the two objects,
- is the distance between the centers of the two objects.
Thus, the correct answer is B Mass.
